Add example code for indicator

Code includes a window that is not needed for the player.
Edit Makefile to include proper GTK and indicator paths.
Edit .gitinit to ignore example binary.
Add notification on new track

when a new trach is played, a gnome/unity notification pops up
with the information.
Next step is to have an icon that displays the playlist history
on clicking.
Clean up notification code

Looks like notification stuff must not be reused.
Working Notify version

Popup track info looks okay now. Add Icon to get rid of station.
Last code cleanup before starting on Indicator.
Indicator cleanup

Clean up source and display. This version works fine.
