Animate the logo on hover

The logo is now rendered as pure SVG, rather than image referencing a
svg. The SVG has an id and the shapes of the logo have a shared class.
The shapes change their fill color on hover with a transition.

Identical to how it looks on about.gitlab.com

Redirect to a default path if HTTP_REFERER is not set

Safari 9.0 does not yet honor the HTML5 `origin-when-cross-origin` mode,
and it's possible load balancers/proxies strip the HTTP_REFERER from
the request header. In these cases, default to some default path.

Fix duplicate repositories in GitHub import page

By default, all the current user's repositories are accessible via the
/users endpoint. There's no need to traverse all the organization
repositories as well.

See:

Correctly find last known blob for file deleted in MR.

Fixes #3092.

When building a new MR, `@merge_request.commits.last` would fail because this delegates to `merge_request_diff` which is still `nil` at that point. I fixed that, and changed some of the logic because showing deleted blob contents didn't previously work for the Compare page, and the UI would show the wrong commit sha for "View File @...".

Remove some padding from code blocks

This creates a weird "leading indent" on the first line of code blocks, at least in Chrome 46, and ends up making the first row not line up nicely with everything else.
