Communication working flawlessly :D

Could use some re-checking
and optimizations

+ Blit the first row of pixels
+ Do a random sequence of lights (commented)
+ Interrupt and queue incoming bytes of the sci
+ Auto-reset the sci reception when idle
+ printDebug(str) prints to debugging console
+ Ported the RTC functions to the colfire peripheral
. Fixed a lot of bugs
. Fix: The width is always set to 0
. Fix calculations of the burst data reception
. Fix: Using incorrect SCI module (the hours lost...)
. Now the ID is 0 when the jumper is not soldered
. Set the frequency to 24MHz using a crystal
