fix for correct track nr instead of only nr 0
Test with start navigation with track number from MainMenuActivity
Selecting track from relative position is stopid, select track from absolute filename

names will be numbers, easy, simple, effective
tracks start at 1 , if 0 no track is selected
working test of track button direct navigate track
Cosmetic updates
Automatic track buttons with nicer view
Test tracks
new code now always adds last row
