And here is version 0.0.5 with one of the major thread bugs fixed. As i suspected, most of the problems with changing songs came from trying to get sound data while the despotify library was doing its thing.

Fixes:
Separation of thread activity in client layer and despotify when changing songs.

Changes:
+ Some small change to how the UI is updated when Previous or Next is clicked.
+ Polling update of the GUI is started as soon as the application starts and not when the first song starts.
+ The client layer should exit more cleanly now and avoid triggering a segmentation fault when the application is terminated.

Things to note:
- I sometimes end up with a song not starting. The application is still responsive but no sound data arrives. No idea why. By picking another song, I get music again.
- Doing another search after having scrolled around in the previous result works but the view is left at the old place and not reset to the top.
- There are similar scrolling issues with the playlist and song view.
