GitLab

- Header changes immediately without a page reload
- Lets the user know that we actually saved their setting when changed

added width and height below images in diff

When projects were created in projects_controller
create.js.haml passed notice as url parameter and
therefore notice was not displayed in the page after
redirect to the project page

Replaced commit status images (diff_file_*.png) with fontawesome icons

Cannot remove user that owns a project.

Make lines shorter, set alert, use path instead of url.

Also fixes #1983
