First prototype of Rich Desktop Notifications

..yeah, "rich".
Frankly, they are horrible to work with.

So, here's how Beta looks like now for Windows crowd, if they update to 0.7.0.7 0.7.0.8:

Regular users will have to wait a little more as this undergoes minimal testing and further tweaking.

* It's the only way I can style these.
* Ugly HUGE buttons.
* If there are a lot of lines they clip off.
* Can't stay onscreen indefinitely, will be hidden in the Notification Center in 25 seconds (those who wanted it - rejoice), that is minimized to a tray icon.

Note the separation of group and personal messages. Maybe it's a good idea overall.

Click on the notification closes it and opens the corresponding message center area (inbox or group) and closes the notification.
"Open all" does what it did in the old ones: opens a message center tab for every class, and closes the notification.
"Dismiss as read" marks all messages as read and closes all notifications. There is no way currently to make it granular (inbox/group), but I can in theory make it so.

Edit: Oh, and another thing. By now the Options page is a horrible mess, and requires complete teardown and rebuilding more than ever. However, getting the notifications working again is a higher priority.

Feedback please!
