Use colorOnSurface for the first time ever. I decided to pick a color
that was as non-intrusive as possible that was still differentiateable,
and I think it looks like a net improvement. It will probably be
tweaked a bit in the future as I expand it to other elevated views.
Make playback/about UIs follow the new liftOnScroll and edge-to-edge
idioms. This finally allows me to collapse a lot of duplicate code
into MainActivity and in general reduce code mess.
Fix two annoying appbar issues:
- Appbar will collapse if the navigation sequence is too fast
- Tab ripple would paint over the indicator unless the ripple was unbounded [???]
Merge LibraryFragment, SongsFragment, and others into a new fragment
called HomeFragment. This is the beginning of the Auxio UI overhaul.
This has caused some regressions here and there, but these will be
rectified over time.
