Adapting the avr-capsense code to the Kiibohd Controller API

- Adding "template" keymap
- Removed "stray" functions, variables
- Cleaned up warnings
- Now builds
- Added buffered macro integration (rather than dealing with USB directly)
- Updated the print messages to use the Kiibohd print header

TODO
- Add generic matrix integration (this will require some changes to the matrix code)
- Add more comments...lots more
- Clean up dead code
