got LEDs working, ribbon trail program initially implemented

Browse Source 
- fixed soft I2C master set hi/lo routines
- fixed bug in matrix_send not setting all LEDs from map
- fix AWU interrupt not firing; requires EXTI line to be configured too even if unused
- fixed wrong dividers used in system clock set function
