Fix for keypad

Some fixes in the Makefile to support Arduino 1.0.0 or higher and added the Rambo. Still needs some more work for the different arduino hardware variants.

Conflicts:
	Marlin/Configuration.h

Added french translation

You need 3 temperature resistance:combinations. This gives a better result then using beta.

Added automatic build numbering.

FIX: Allow marlin internal 0°C represenation

Added Polish translation. Cosmetic changes to English.

Header multiple include protection should match the filename, not just _ARDUINO_H, which is almost bound to go wrong some day.

Fix Gen7 compile if you have avr-libc version 1.7.1 or higher. See http://code.google.com/p/arduino/issues/detail?id=604

Store the pre-heat constants outside of the ULTIPANEL define, so we can use them when storing EEPROM in a build without the ULTIPANEL.

Update on makefile, should make it easier to compile for different boards without changing the makefile. (Still missing Arduino 1.x.x support).

Yes, makes sense, lets NOT use the value directly from the configuration define but modify it before setting it. This will not confuse people (including me) at all!

Lcd fixes

Controller. Remove common definitions. Harmonize declaration order.
