 Activity: introducing @mentions auto-suggestions.

 Activity has long-supported @mentions, where you can mention the name of
 another user to get their attention in a conversation. You've always had
 to know the exact username of the person you're trying to mention, or
 you've been forced to go look it up. Now, when leaving an activity update
 or reply, press `@` and then start typing someone's diaply name (or
 user_nicename), and username suggestions will automatically appear below
 where you're typing.

 If the Friends component is active, and if the logged-in user has any
 friends, those friends' details are used to pre-prime the username
 suggestions for super-fast snappy suggestions. Suggestions are also
 provided when writing a blog post comment.

 This change has mostly been implemented using two third-party libraries,
 At.js (https://github.com/ichord/At.js) and Caret.js
 (https://github.com/ichord/Caret.js). Big thanks to those projects'
 authors for their fine work, and also to Automattic's O2 team, who made a
 number of CSS+JS tweaks/adaptions to At.js, which we've adopted. Props
 also to karmatosed for design suggestions on the earliest implementation
 of this feature, three years ago. :)

 Fixes #3278
