Add plain patch view
The new view mimics the output from `git format-patch`, making it possible to cherry-pick directly from cgit with something like `curl $url | git am`. Inspired by a patch to `git-apply` by Mike Hommey: http://thread.gmane.org/gmane.comp.version-control.git/67611/focus=67610 Signed-off-by: Lars Hjemli <hjemli@gmail.com>
