Share invocation working, kinda.

Removed titleBar assets since it is included in OS now, and as a result
share invocation working. However, no data is being passed along, so
needs fix. Downloading tracks magically began to work now, not sure what
was wrong earlier. Fixed bug, music keeps playing when logout. After
logout and login again, app is super slow/choppy and needs to be
restarted. Need to work on this. Dedicated noalbumartwork image behind
album artwork image so when loading a new track, does not look empty.
