David Robillard e0cb9efb00 Various color tweaks.
This commit changes some color names, nuke your theme.  This isn't quite ideal
yet, but takes some steps towards where I think things should go aesthetically:

Make automation tracks/regions colors correspond to their parent's type.

Make selected MIDI notes outlined in red like most everything else, and scrap
separate min/mid/max fill colors for selected MIDI notes.

Color automation ghost MIDI notes based on original note color.

Try to kill 90's looking brightish gray gradients in general.
