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.

Update Marlin/language.h

Included Portuguese language

Clean up special serial port cases

Assume SERIAL_PORT 0 if not defined. Collapse un-numbered register
special case. Clarify comments.

Better explain the watchdog "problem" and rename the config define so it explains that the feature belongs to the watchdog.

First cleanup. Moved all code to cpp files, so there are no dependencies on pde files. And no more odd requirement to cat files together. (Still need to fix the Makefile). Also cleaned up some defines and made defines upper case as by C coding conventions.

Use the right pins for Gen7 1.4
