Added new board for those of us with sanguinololu boards with ceramic resonators
Fixed the plane vector equation to a simpler one (only dependent on the normal)

Removed the calculation of the inverse matrix since the rotation matrix is orthogonal, therefore inverted == transposed.
Much simpler and mathematically robust.
Implemented a least squares fit of the bed equation for auto bed leveling.

Made numbering of heat bed thermistor more logical as D8 is bed, D9 is Extruder 2 and D10 is Extruder 1, so T0 should be E1, T1 E1 and T2 bed to be sequential as MOSFET-Outputs
Added posibility to set ENCODER_STEPS_PER_MENU_ITEM in Configuration.h like ENCODER_PULSES_PER_STEP as it depends on it for usability
Incorporate PS_DEFAULT_OFF for starting state on LCD menu entry
Minor code and comment polishing
Accurate bed leveling: x loop inside y and zigzag motion
