We're planning to implement a feature that allows adding required fields for existing users. This PR does some preparatory refactoring to make that possible. There should be no changes to existing behaviour. Just a small update to the admin UI.
provide the ability to edit theme settings in the json editor, and also copy them as a text file so they can be pasted into another instance.

The lint warnings were:
```
inline-block is ignored due to the float. If 'float' has a value other than 'none', the box is floated and 'display' is treated as 'block'
scss(propertyIgnoredDueToDisplay)
```
A public key must be added to GitHub when installing private themes.
When the process happens asynchronously (for example if the admin does
not have admin permissions to the GitHub repository), installing
private themes becomes very difficult.
In this case, the Discourse admin can partially install the theme by
letting Discourse save the private key, create a placeholder theme and
give the admin a public key to be used as a deploy key. After the key
is installed, the admin can finish theme installation by pressing a
button on the theme page.
There are still some, but those are in actual code that's used outside core, so the change there would need to go through the deprecation cycle. That's a task for another day.
Translations are often multi-line. Using a regular `<input>` doesn't allow newlines, so if you try to edit a multiline theme translation, all the line breaks will be removed.
This commit updates the theme translations UI to use `<textarea>`, just like the core translation editing UI.
* DEV: Show warning message when using ember css selectors
When editing the theme css via the admin UI a warning message
will be displayed if it detects that the `#emberXXX` or `.ember-view`
css selectors are being used. These are dynamic selectors that ember
generates, but they can change so they should not be used.
* Update error message text to be more helpful
* Display a warning instead of erroring out
This allows the theme to still be saved, but a warning is displayed.
Updated the tests to check for the error message.
Updated the pre tags css so that it wraps for long messages.
Themes can now declare custom colors that get compiled in core's color definitions stylesheet, thus allowing themes to better support dark/light color schemes.
For example, if you need your theme to use tertiary for an element in a light color scheme and quaternary in a dark scheme, you can add the following SCSS to your theme's `color_definitions.scss` file:
```
:root {
--mytheme-tertiary-or-quaternary: #{dark-light-choose($tertiary, $quaternary)};
}
```
And then use the `--mytheme-tertiary-or-quaternary` variable as the color property of that element. You can also use this file to add color variables that use SCSS color transformation functions (lighten, darken, saturate, etc.) without compromising your theme's compatibility with different color schemes.
A first step to adding automatic dark mode color scheme switching. Adds a new SCSS file at `color_definitions.scss` that serves to output all SCSS color variables as CSS custom properties. And replaces all SCSS color variables with the new CSS custom properties throughout the stylesheets.
This is an alpha feature at this point, can only be enabled via console using the `default_dark_mode_color_scheme_id` site setting.
The admin permalink list was a little tricky to use because the URLs are easily reduced with a ... if they are too long. This adds a copy to clipboard button for the URL and a title on hover so the full text of the URL can be seen.
