Update language.h

Added servo pin assignments to Sanguinololu

Configuration_adv.h

Adjustable Z probe offset via custom M-code

Update Readme descriptions for M200, M207 and M208

FWRETRACT in mm/s

Change CONTROLLERFAN_PIN for board 35 to -1, as it would conflict with board's 33 extruder pin, causing burnout (it's the same board, just different number of fans/extruders, therefore should be pin-compatible)
