Subject: [PATCH] Add task for force updating a working copy

Downloads the latest from remote without trying to merge or rebase
anything. Resets the master branch to what you just fetched. Changes all
the files in your working tree to match the files in origin/master, so
if you have any local changes, they will be lost.
