The abstract adapter has been cleaned up and should work properly now.
The only restraint is that is must be instantiated on the UI thread. Not
sure if there is way to detect whether that is the case or not.
Renamed a string resource to match the activity naming scheme. Added one
for the button.
Started adding custom resources for the circular progress bar colors.
Just the center color is set right now, just getting it to work took
some doing, but should be much easier to add colors for here on out.
