Songbird 1.9 compatibility.

* Bug #72: Add compatibility for Songbird 1.8
* Feature #73: Change add-on icon

* Updated for Pure Player (new) Version 0.8.5.5 by Hiromacu
* Integrated Linux fork into this release
* Since Linux does not support transparency (round corners) very well, I tried to adapt to that situation. Feedback on how it works for you would be great.

* Linux fork that tries to fix some bugs.

* Songbird 1.4.3 compatibility
* PurePlayer 0.7.7.1 compatibility (version by maurobit, see PurePlayer comments)

The skin it currently finished, so its time to release version 1.0:

• Full code redesign

Just some stylish stuff:
