implement sync ping

a sync ping packet is sent when the clock enters sync mode.
this allows an ap program to sync the clock automaticly and exit the sync mode.
The sync ping packet is sent until any packet is received.

 * modularise more code

-* use bulk transfer in sleep clock mode
 * make buttons lock while sleep mode active
 * better compilition depending on config file. someone with more make knowledge please ;-)
 * fix warnings in simplicti code
 * use RTC of the msp430 instead of the interrupt code
+* fix the eggtimer. it runs to slow (like 2 seconds per second...)
