Summary:
Ref T3190. #shipit
Likely future work:
- Extract project mentions from remarkup for ApplicationTransactions; this isn't relevant in any apps right now (but will be in Pholio before tooo long). Ref T3189.
- Allow projects to have alternate short names. As written, this is fine for most projects ("Differential" is `#differential`) but not so great for other projects ("Phabricator Public & Media Relations" is `#phabricator_public_media_relations`). This also breaks refs when you rename a project. Better would be letting long project names have short aliases (`#pr`) as permitted alternatives.
Since this mention uses `#` instead of a letter, I needed to do a small amount of regexp gymnastics.
Test Plan:
you only #yolo once
