Subject: [PATCH] messageList: Allow dismissal via backspace

Currently only the delete key can be used to dismiss notifications.
Some laptops don't have delete keys, resulting in needing to hit a
modifier to trigger delete.

Plus, on those keyboards that do have delete keys they're often a
little harder to strike than backspace.
