Show the names of patterns in their tool tip

Adjust PatternView::update to show the name of the pattern as the tool
tip (regardless of whether it is a beat and bassline or a melody
pattern).

Override the public slot TrackContentObjectView::update for
AutomationPatternView and BBTCOView. Implement it similar to
PatternView::update.
