Also expose username for the /discover endpoint

Fixes #6328
Add button for toggling inline comments in diff view.

This is useful when there are many comments and they're becoming a distraction when trying to read the diff.
Remove dir prefix and suffix from tests inside dir.
Don't send an email for "mentioned in" notes

Currently, an email is sent every time a mentionable is referenced
by an issue, a commit or a merge request: if I comment "This MR is
related to #5", watchers get one email for the comment, and another
one stating "Issue #5 was mentioned by issue #13".

This is annoying — but the biggest issue is when pushing an existing
branch. Every issue referenced by commit messages in this branch will
get a new mention (which is fine), and dozens of emails will be sent
for all these new mentions (which is not).

This commit fixes the spam by avoiding to send an email when a new
mention is created. In most cases the email notification for the
mentioner is enough.
