Cleaning up in preparation to be more serious.

I brought in all the work I had done previously, and made significant
changes.
Moved to an ENUM system for passing the intention to the intent.
Moved to a Spinner instead of using many buttons.
Moved to simplify / condense code.
Created everything in a new Android Project.

Gearing towards a demo app. I could read all the stuff about making a
library, but, it's just not something I think I'll have patience for
right now.
Various other changes. I have some missing comments that attribute some
of the work to other people. I'll be moving them out of the source files
and into a THANKS.txt file.
