Cleaner headers in Notification Emails

Make the informations available in the notification email headers (sender, recipient, subject, etc.) more readable and meaningful.

* Remove the email subject prefix
* Don't write the project namespace in email subjects
* Write the issue/merge request title in the notification email subject
* Make the email appear as sent from the action author (the actual email address is still `gitlab@gitlab.com`)

For instance, this is the notification email for a new issue comment before:

> From: gitlab@gitlab.com
> To: myemailaddress@gmail.com
> Subject: GitLab | GitLab HQ / GitLab-Shell | New note for issue #1234

And after :

> From: Nick Brown <gitlab@gitlab.com>
> To: myemailaddress@gmail.com
> Subject: GitLab-Shell |  Add local update hook  (#1234)

The recipient of the notification can easily get the gist of the message without even opening it — just by looking at how it appears in her inbox. None of the actual email addresses (From, To, Reply-to) changes, just the display name.

Having a consistent subject for all notification emails sent about some resource also allow good email clients to group the discussion by thread (although grouping in Mail.app still needs some work).

Main purpose is move big amount of methods from user, group, project
models and place filtering logic in one place.
It also fixes 500 error on group page for PostgreSQL
