Subject: [PATCH] naughty: add suspend() and resume()

This commit adds naughty.suspend() and naughy.resume() which allow
suspension of notifications, which is useful e.g. when watching a movie,
where notifications popping up all the time would be disturbing.

While suspended, notifications are collected and displayed after
naughty.resume() is called.
