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

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

Preheat LCD menus base on code by D-Base

Set flow rate (extrude-mutliplier) for each extruder individually

Extension of M221, Tune menu

Update on 140315

Add support for disabling encoder control for feedrate multiplier

Added CHDK support

Firmware retraction now stores the retract and recover speeds in mm/s
instead of mm/min. This makes it match the units of the maximum
feedrate, and fixes problems with modifying the value via LCD control
panel. From gcode, the values are still taken in mm/min to match the
units of G1 and similar, and they are converted to mm/s before they are
stored.

I also lowered the default retract feedrate to make it less likely to
cause problems for geared extruders when the user hasn’t bothered to
set a reasonable maximum feedrate, though users should be setting both
of these values to suit their hardware.

Added CHDK support to take pictures instead of doing an IR command, see more about how to use it here http://captain-slow.dk/2014/03/09/3d-printing-timelapses/

Added so M240 can be used to trigger CHDK instead of sending an IR signal, see more about CHDK here http://captain-slow.dk/2014/03/09/3d-printing-timelapses/

Increase Z_HOME_RETRACT_MM to 2mm default to avoid end stop not switching during retract.

Fixed Finnish translation

- Fixed Few finnish transalations
- Removed duplicate contrast define

temperature.cpp: Fix PID_DEBUG compile error.

Update README.md with Autotemp typo fix
