The example scripts include hardcoded values that
do not work for everyone. Instead of requiring the
files to be edited (and dirtying the git tree),
allow them to take command-line arguments.

Also adds better guidance for Mac OSX virtual
serial ports.

- Rx buffers weren't fast enough, had to use DMA :D
- Basic LCD remote capabilities are working, single node
- Multi-node broadcast seems to have a bug still
- DMA ring buffer allowed for significant processing simplification
  * There is an overrun risk, but the buffer is large and generally there isn't too much data being sent (just very quickly)
- Split out LCD layer stack capability into itself and an "exact" version used for updating remote nodes

- Requires kll update
- Including udev id update

- Requires lcdFuncMap.kll instead of stdFuncMap.kll

- Fixed cli reflash mode set
- Cleaned up debugging code
- 4 500 000 baud seems to be reliable
- Fixed master selection (assumes slave node unless USB enumerates)

- Changing header file ifndef define to pragma once's
- Removed duplicate output_com.h's

- Basic screen initialization and clear is working
- Currently SPI is set to a low speed for easy logic analyzer debugging
