Add 'w' keybinding in files panel to commit as a WIP

If your git.skipHookPrefix is set to, say, WIP, in your config, then
hitting 'w' in the files panel will bring up the commit message panel
with 'WIP' pre-filled, so you just need to hit enter to confirm
(or add some more to the message) in order to commit your changes
with the --no-verify flag, meaning the pre-commit hook will be skipped
