Parse @-mentions in bugdown and style them. * This makes bugdown.convert take a `message` parameter. Properties for parsed mentions are added to the message object by the `Pattern` for use in do_send_messages. * Refactor repeated markdown rendering code into `Message` model methods.

[manual] Rename Django app from zephyr to zerver. This needs to be deployed to both staging and prod at the same off-peak time (and the schema migration run). At the time it is deployed, we need to make a few changes directly in the database: (1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr'; (2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr'; (imported from commit eb3fd719571740189514ef0b884738cb30df1320) 2013-07-29 23:03:31 +02:00			`import zerver.models`

Make the @-mention regex not match in the middle of the word. Fixes issues with e.g. foo@hamlet.com (where hamlet is a user) The \b was ineffective because @ made it always on a word boundary. Instead, use the negative lookbehind trick from the URL regex.

Pre-fetch data from the DB and hand to markdown thread We want to avoid opening a DB connection in the markdown thread as its DB connection might live for a long time (imported from commit 7700b2ca793ee5e9add7f071b92f22a4bf576b3d) 2013-10-09 20:48:05 +02:00			`def user_mention_matches_wildcard(mention):`
