Say hello to a new version:

- Now saves volume level to database on exit, so it can be restored when GrooveWalrus is loaded.
- Added pop-up error message that'll hopefully spit out something if Grooveshark isn't working.
- Trying to embed the proper icon into the gw.exe, hopefully it's better, because manually inserting it sucks.
- Added more local data tracking, adds a record for each play, stop, skip, and complete play event.
- Should be able to make some neat graphs or something down the road.
- Changed layout.xml, added new items for news Saved Playlists functionality.
- Added new menu item Ctrl-S to save playlist to database.
- Added a Saved Playlists button on the Playlist tab, clicking it shows the playlists that have been saved to the database, clicking on a saved playlist loads it, clicking again allows you to rename it.
- Added a few tables to the database, one to store playlists, another to store more playback data.
