DEV: Refactor watched words ()
- Ignore only invalid words, not all words if one of them is invalid

- The naming scheme for methods was inconsistent

- Optimize regular expressions

PERF: improve findAllMatches speed ()
When we introduced unicode support in the regular expressions used in watched words (9a27803) we didn't realize the cost adding the `u` flag would be.

Turns out, it's pretty bad when you have lots of regular expressions to test. A customer had slightly less than 200 watched words, and it would freeze the browser for about 2s on the first check of those regular expressions (roughly 10ms per regular expression).

This commit introduces a new field (`word`) to the serialized watched words which is then converted to a very fast and cheap regular expression on the client-side. We use that regexp to quicly check whether a matcher is even worth trying so that we don't incure the cost of compiling the expensive unicode regexp.

This commit also busts the `WordWatcher` cache since we added a new field to be serialized.

One nice side effect of using `matchAll` instead of a `while / exec` loop is that the likeliness of having a bad regexp matching infinitely is vastly reduced 🙌

FIX: Handle all UTF-8 characters ()
Watched words were converted to regular expressions containing \W, which
handled only ASCII characters. Using [^[:word]] instead ensures that
UTF-8 characters are also handled correctly.

UX: Skip applying link-type watched words to user custom fields ()
We currently apply type: :link watched words to custom user fields. This makes the user card pretty ugly because we don't allow html / links there. Additionally, the admin UI also does not say that we apply this to custom user fields, but only words in posts.

So this PR is to remove the replacement of link-type watch words for custom user fields.

FEATURE: Add support for case-sensitive Watched Words ()
* FEATURE: Add case-sensitivity flag to watched_words

Currently, all watched words are matched case-insensitively. This flag
allows a watched word to be flagged for case-sensitive matching.
To allow allow for backwards compatibility the flag is set to false by
default.

* FEATURE: Support case-sensitive creation of Watched Words via API

Extend admin creation and upload of Watched Words to support case
sensitive flag. This lays the ground work for supporting
case-insensitive matching of Watched Words.

Support for an extra column has also been introduced for the Watched
Words upload CSV file. The new column structure is as follows:

 word,replacement,case_sentive

* FEATURE: Enable case-sensitive matching of Watched Words

WordWatcher's word_matcher_regexp now returns a list of regular
expressions instead of one case-insensitive regular expression.

With the ability to flag a Watched Word as case-sensitive, an action
can have words of both sensitivities.This makes the use of the global
Regexp::IGNORECASE flag added to all words problematic.

To get around platform limitations around the use of subexpression level
switches/flags, a list of regular expressions is returned instead, one for each
case sensitivity.

Word matching has also been updated to use this list of regular expressions
instead of one.

* FEATURE: Use case-sensitive regular expressions for Watched Words

Update Watched Words regular expressions matching and processing to handle
the extra metadata which comes along with the introduction of
case-sensitive Watched Words.

This allows case-sensitive Watched Words to matched as such.

* DEV: Simplify type casting of case-sensitive flag from uploads

Use builtin semantics instead of a custom method for converting
string case flags in uploaded Watched Words to boolean.

* UX: Add case-sensitivity details to Admin Watched Words UI

Update Watched Word form to include a toggle for case-sensitivity.
This also adds support for, case-sensitive testing and matching of  Watched Word
in the admin UI.

* DEV: Code improvements from review feedback

 - Extract watched word regex creation out to a utility function
 - Make JS array presence check more explicit and readable

* DEV: Extract Watched Word regex creation to utility function

Clean-up work from review feedback. Reduce code duplication.

* DEV: Rename word_matcher_regexp to word_matcher_regexp_list

Since a list is returned now instead of a single regular expression,
change `word_matcher_regexp` to `word_matcher_regexp_list` to better communicate
this change.

* DEV:  Incorporate WordWatcher updates from upstream

Resolve conflicts and ensure apply_to_text does not remove non-word characters in matches
that aren't at the beginning of the line.

FIX: Don't cook user fields to apply watched words ()
The previous method for reused the PrettyText logic which applied the
watched word logic, but had the unwanted effect of cooking the text too.
This meant that regular text values were converted to HTML.

DEV: Automatically require 'rails_helper' in all specs ()
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.

By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.

39e0442de9 FIX: Various watched words improvements
- Client-side censoring fixed for non-chrome browsers. (Regular expression rewritten to avoid lookback)
- Regex generation is now done on the server, to reduce repeated logic, and make it easier to extend in plugins
- Censor tests are moved to ruby, to ensure everything works end-to-end
- If "watched words regular expressions" is enabled, warn the admin when the generated regex is invalid

FEATURE: Watched words improvements ()
This commit contains 3 features:

- FEATURE: Allow downloading watched words
This introduces a button that allows admins to download watched words per action in a `.txt` file.

- FEATURE: Allow clearing watched words in bulk
This adds a "Clear All" button that clears all deleted words per action (e.g. block, flag etc.)

- FEATURE: List all blocked words contained in the post when it's blocked
When a post is rejected because it contains one or more blocked words, the error message now lists all the blocked words contained in the post.

-------

This also changes the format of the file for importing watched words from `.csv` to `.txt` so it becomes inconsistent with the extension of the file when watched words are exported.

e219588142 DEV: Prefabrication (test optimization) ()
* Introduced fab!, a helper that creates database state for a group

It's almost identical to let_it_be, except:

 1. It creates a new object for each test by default,
 2. You can disable it using PREFABRICATION=0

4ea21fa2d0 DEV: use #frozen_string_literal: true on all spec
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.

Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
