CC1020

o   Turns off only after transmission has ended and not in between

o   Using events for DMA takes too long. It should use a callback when
    DMA finishes to turn off the transmit mode as early as possible.

Core/UART

o   Added profiling and energest initialization

o   Changed low-power mode from LPM1 to LPM3

# msb430\dev\cc1020.c
Data type problem in the calibration function, therefore looping 10 seconds on boot. Fixed.

# msb430\contiki-msb430-main.c
Directly accessed power management while other modules used the Contiki layer resulting in the node sleeping most of the time. Fixed.
Added uIP support.

# msb430\buildscripts\makefile.win
Changed to erase only main-memory but keep infomemory so the node configuration is not erashed during flashing.
