spi, can and general improvements
SPI:
-move to single transfer read
-clear interrupt register on read
-perform multibyte read transfers with DMA
-make frame format consistant
CAN:
-move from mailbox to CAN FIFO
-implement buffering
-support for reading multiple frames per transfer
General:
-use PLL at 100MHz
-remove debug task
-do not compile release with debug console enabled
-bumped version to 0.13
