Add new optional field usershort to rcs_recentchanges.

Now the git plugin supports commits with author fields that look like:
Author: http://my.openid/ <me@web>

Then in recentchanges, the short username will be displayed, linking
to the openid.

Particularly useful for the horrible google openids, of course.
