Updated the MSP430 hwtimer implementation, to cope with the lack of consistency
of of TI with the TimerX register names.
Added mising reference to cpu/msp430-common/include/cpu.h
so as to get the needed definition of F_RC_OSCILLATOR
Added missing definition of 'PRIu32' in some RIOT include files
to avoid a bug in mspgcc's standard library
added some debug output for the network stack
Merge pull request #254 from OlegHahm/network_debug
