This improves the `TextSentinel` so that we don't consider CJK text as being uppercase and thus failing the validator.
It also optimizes the entropy computation by using native ruby `.bytes` to get all the bytes from the text.
It also tweaks the `seems_pronounceable?` and `seems_unpretentious?` check to use the `\p{Alnum}` unicode regexp group to account for non-latin languages.

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.
