Adds the option merge.defaultupstream to add support for merging from the
upstream branch by default. The upstream branch is found using
branch.[name].upstream.

This is just testing code; it works but I'm not yet sure if it breaks other

Note: First time using git send-email; I hope I set it up correctly with the
In-reply-to and Cc's and such.
