@mention should be a link
When we use @mention in a comment (to notify a user), it is rendered as mention. I would expect it to be a link to the user page.
I initially thought the current behavior was a bug, actually. Also, most systems I use that have this @mention system replace the login name by the full name of the user when rendered. @orenaud is replaced by Olivier Renaud which is a clickable link. To me both behaviors are fine, but the transformation to the full name reinforces the idea that the mention is correctly resolved.

note: Technically i think we can only implement this in Mardown renderer type. RST generally doesn't allow much of html editing. Also the current logic is strictly disconnected from any DB calls etc, i'm not sure if we should do this. Active tooltip would be the simplest solution.
