Big update to Mailbox Alert!

Configuration has changed, and you can now set alerts as a Thunderbird filter action!

I also added a separate Manual. It needs some work, but it's better than nothing :)

There are some open issues; I just discovered the global mute doesn't work anymore, the reviewer had some good points, and I did not yet find a good way to pass around the full message body (a much requested feature). Another feature that did not make it yet is alert customization. The first two of these will be addressed in 0.15.1. I shall ponder on the bigger ones for 0.16 :)

Once again, happy mailing
