This reverts commit 651cde8b98b9499796e96cad9e267dcd6bbb86d4.
Merge branch 'Marlin_v1' of https://github.com/ErikZalm/Marlin into Marlin_v1
lcd panel bed support
advance and ultipanel not any more in default config
cooldown
added m240 photography support. default off
header file simplification
simplified the includes, makefile now works with arduino23
add wiring.h, that can be used to overwrite:
 arduino-0023/hardware/arduino/cores/arduino/wiring.h
this is necessary if the avr libraries are recent, but arduino is old. Alternative: newer arduino
starting with sanguino arduino 1.0 compatibility
one step closer to a functional makefile..
fix duplicated definition of MOSI MISO pins in case motherboard==33
fix autostart failure if in wrong directory
