- Added AddModule CMake function which simplifies specifying module requirements

- The UART out may be useful for Bluetooth keyboards at some point

- Includes serial putchar and getchar cleanup (overall)
- Moved avr-capsense to DPH (renaming)
- Basic cleanup for including CLI on the avr architecture

* Initial cli code

- All modules have a default avr compatibilty right now (since that is what they were developed on)
- As modules get tested and added, arm support has to be turned on in the respective setup.cmake file

- Very small updates to files, mostly modifying to remove name duplications

- Abstracted USB Module
- Abstracted compiler specific includes for Scan, Macro, Debug, and USB modules
- Updated CMake build files to support changes
- Added abstractions necessary to main.c as well as a compiler specific include file

- Commenting cleaned up
- usb_keyboard_debug is not finished yet in terms of cleanup (needs DEBUB_PRINT #ifdef's)
- Added LoadFile script generation
- Formalized KeyIndex and USBKeys data containers
- Split parts of scan_loop into Macro, USB, and main.c
- Added interface to USB modules
- Added interface to Macro modules
- Added proper Debug module enable/disable

- Include option is currently "hacked" and needs to be fixed
- Builds on Linux, but Mac and Windows needs to be tested
- Loader script generation isn't complete
