Fix and improve admin/mod distinguishers (#386)

* Fix regression with comments from deleted mods

Starting with https://github.com/spikecodes/libreddit/pull/367/files
comments from deleted moderators and admins(?) aren't highlighted.

* Highlight mod and admin usernames in posts

Works like on reddit + shows highlight for mods on the search page.
