*) Don't set the track information if the user canceled the dialog.

Style:
*) KListViewItem subclass was a QObject for no apparent reason
*) Follow the indentation and spacing standards of the rest of the files
*) Don't use public member varibles, but accessor methods
*) Removed unused includes
*) Wrap columns at approximately 80
*) Don't use the m_ prefix for local variables, just member variables
*) Use pointer->member() rather than (*pointer).member()
