Add improved UART code.
Build osuar_uart instead of osuar_comm.
Use new UART setup function.
Remove old comm code.
Add a todo comment..
Add I2C file for later.
Progress?
Add custom sprintf function.
Add chsprintf to Makefile.
Use SPI1 instead of SPI3, because the latter just doesn't work.
Add more SPI functions.

Fancy fading LEDs, less obnoxious blinker, subsystem initializations, etc.
