Improved Git Repositories

Public repository pages are wider, with the clone address above the files

A public Git repository page uses the full width of the window, and its clone address sits on one line above the file list.

A public Git repository's page at /g/<team>/<repository> now uses the full width of the site rather than a narrow reading column, with less space around it. The name and description sit at the top, followed by one box with the last commit and the clone address on a line across its top and the files below.
