Fix for microstepping pin mapping, not using Teensy pin mapping, but Arduino's default pin mapping so Arduino library can be used

This reverts commit eea3ba55.

This reverts commit 2715f6dd.

Speed up QUICK_HOME feedrate for diagonal move

Speed up the diagonal move while still keeping each individual axis at
or below its homing feedrate.

Added new language (Basque-Euskera)

pull Request to Add beta 3950 1% thermistor table into marlin firmware

Added:
* new language (Basque-Euskera)
* some minor corrections for Spanish
* added 2 new constants for every language (required for a minor change
I am preparing to ultralcd.cpp)

it's caracteristics are :

R25℃ ;100KΩ±1%

B Value(R25/50℃)：3990K 1%
Dissipation Factor(mW/℃)：1.1~1.6 In still Air
Thermal Time Constant(S)：10~17 In Still Air
Operating temperature range：  (-50~+260°C)
Dimension：  1.8mm Dia X4.1mm
Lead Length  ：30mm

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)

thermistortables.h: Add comments that table 60 uses beta=3950.

fix bug for dual extruders not working

fix bug in M200 with multiple extruders

some guy find that marlin not working good for dual extruders delta .
when type T0 or T1 to active extruder and  E0 or E1  move causing XYZ
motion . so i locales the bugs and fix it , I have dry run the fix.

Updated to latest version.

Added catalan language

Extended Preheat options
