Forms action padding fix

The padding on the forms action is not adjusted based on screen width:

I added a media query for .forms-action at min-width: $screen-sm-min and moved the padding-left: 17% into it:

Full width padding remains as is:

As this is a purely css change, I don't believe it will break any tests. form-actions occur everywhere there are form actions.

Dashboard icon styling fix

When viewing a fresh install of GitLab on a mobile device, the styling for the dashboard item icon is broken in such a way that if the description div is more than 100px high, its contents wrap beneath the icon as shown below.

I modified the css for the icon and added a new class to the description div and now it behaves as expected as shown below.

As this is a purely html/css change, I don't believe it will break any tests. The only occurrence of .dashboard-intro-icon is in ./app/views/dashboard/_zero_authorized_projects.html.haml

Fix xmlns:media namespacing for atom feeds

A recent commit gitlab-org/gitlab-ce@d31d711a70779132ea43387f93eb4ccc1e472761 introduced a bug that broke four of the atom feeds. The namespace for xmlns:media was not defined properly. This patch fixes the issues for all four feeds.

Merge request commits view

Changes the commits view of a merge request to use the same layout as used in the project commits view.

As noticed from #923.

This also changes the commits icon on the tab to be fa-history, the same as used in the sidebar
