Add close button to notifications

[aauren]

It would be helpful to have a close button on the notifications so that they could be manually hidden when users are finished with them.

It would also be helpful if we can add the following buttons as well when user hovers over the notification :

1. Love Current Playing Track on last.fm
2. Pause/Next/Prev buttons for spotify control.

I would love to have the "love current playing track" functionality as I am an avid Last.fm user. I am unsure about how useful will be the pause/next/prev buttons but it can be a nice addition.

Above buttons should be totally configurable.

You can refer to my python project Lastify for more details on how to implement the love track functionality. I will be happy to help if you require anything from my side.
