Port Moderation functionality to TypeScript

[pixeldesu]

Fixes #162

Testing:

• (Un)set user privileges
• (Un)ban a user
• Moderation Panel:
  • (Un)vote on reports
  • Unfold comment section
  • Comment a report
  • Character count
  • Deleting a comment
  • Deleting a report

As it was mainly used in moderation-heavy areas before, I removed tempusdominus-bootstrap as well, as it just broke making announcements. And subsequently I was able to get rid of the entire legacy-moderation script entrypoint.

It doesn't really matter (right now) to offload that script portion only to moderations as all endpoints are warden-secured in config/routes.rb anyway.

(Report dialog can't be ported yet as Answerbox still requires that in CoffeeScript)

When following a user

@raccube Following wasn't touched at all in this?

Rebuild my JS and following works fine, where did you try that, and what does the console say?

Ignore that - was my bad
