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

Preheat LCD menus base on code by D-Base

Extension of M221, Tune menu

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 Few finnish transalations
- Removed duplicate contrast define

I made these changes previously, but I can’t find the commit now. This
reapplies the changes to get auto retract working again.

Conflicts:

	Marlin/Marlin_main.cpp

Users can be confused as to which values to enter after a PID tune. Updating the message to help clarity it.
New message: "PID Autotune finished! Put the last Kp, Ki and Kd constants from above into Configuration.h"

Old message: "PID Autotune finished! Put the Kp, Ki and Kd constants into Configuration.h"

Fixed compiler errors on Ubuntu using arduino-core

If position is unknown, then G29 can be dangerous.

This reverts commit 51ae4881ab.
