Changed SLOWDOWN. IF this does not work ok OLD_SLOWDOWN is the old algo.

Fix for wrong systax in #ifdef.

This breaks temperature readout for pronterface!

- Fixed a typo

Fixed small bug in arcs
M105 prints now actual_temp/target_temp

Moved the PID_dT in the Ki and Kd calculation from the configuration.h to temperature.cpp

For upstream

Fix compilation error when PIDTEMP is undefined and ULTIPANEL is defined...

+ Removed most explicit pathnames, use the standard make "VPATH" to let
make find the files for itself.

+ Added a "hardware variant" variable that allows compiging Sanguino and
Gen7 as well as "generic" arduino.

+ Allows overriding the MOTHERBOARD define from the Makefile

+ Removed the 'preprocessor' bit that wasn't needed, now just "include" the
files that are needed, since it allows gcc to show the right file/line
when displaying error/warnings.

+ Uses gcc's own dependency generator to generate the .d files, and
and include these instead of self-patching the makefile

One array was too short. This had nothing to do with long filenames, other than if they were 12 characters exactly, which could only happen if the extension and the text before were filled completely

Better pin configuration for rotary encoder in RAMPS boards

Make F_CPU dependence of stepper.cpp more explicit

M303 Starts autotune. Wait till the Kp Ki and Kd constants are printed.
Put these values in Configuration.h
