Cheers!

The original author of this skin is atreiu. He is disappeared long time ago, so I decided upon to bring this skin back to alive!
New things in my release:
- volume-bar,
- repeat/shuffle buttons,
- own context menu style.
Pure Player preferences for this skin:
- Animated images: Not supported! (This skin doesn't contain animated images.)
- Volume bar: Supported! (You can hide it if you want.)
- Shuffle/Repeat box: Supported! (You can hide it if you want.)
- Jump-to button: Supported! (You can hide it if you want.)
- Round window corners: Supported! (This skin contains version with rounded corners too.)
- Windows shadow: It looks good only if you turn off round window corners option.
- Own context menu style: Supported! (You can disable it if you want.)
- Rounded context menu corners: Supported! (You can disable it if you want.)
- Context menu transparency: Supported! (You can disable it if you want; it works only with rounded context menu corners.)
Works with Songbird 1.8.0 - 1.10.0a
Version bump (1.8.0 - 1.10.0a)
... and small fixings.
