Incorporate Summaries for Notes and Merge Requests Into Dashboard Feed

This MR fixes #305 by adding summaries for notes and merge requests into the dashboard feed.

Remove stale comment in Gemfile

The comment was added in a91a6491, and referred to the below gem `grape-entity` being pulled directly from a Git repo. The `gem` command has already been changed to pull directly from Rubygems, so the comment is no longer necessary.

Fix username validation message to match regexp.

fix for project creation: group projects don't count towards user's project limit

Better location for signin disable

Make it easier for people to find these settings where they are expected, under auth settings.

Mail template changes (add the command line for http) when a project is moved in an other namespace.

See subject, it is just the addition of the set-url for http(s) origin in the mails.

Limit the width of images in emails

In notification emails, large inline images can exceed the width of the viewport. This ensure that large images are resized to fit within the mail client window.

Fix Dashboard Feed URLs For Notes

This MR fixes issue #304 by updating the app/helpers/events_helper.rb event_feed_url() function to also return a URL for the various types of notes. Without this change, no URL is returned, which causes any note events on the feed to link directly back to the feed.

CSS fix: 1px border on hover of last item in tree view

I messed up my fork repository and hat to recreate it. So I closed MR !77 and created this one instead. Sorry for any inconvenience.
