README updated.
README updated to include library details and links to documentation.
This time with correct heater settings...
 Second degree (ruled quadratic surface) bed plane compensation added.  Probe three points to get plane compensation.  Probe 4 [0 = min, 1 = max: (x0, y0), (x0, y1), (x1, y1), (x1, y0) in that order] to get second degree compensation.  Also M115 print version added.
Better version of the ORMAXIS.G file.
Emergency stop added to the web interface (and Home All taken away, as you almost never want to home Z with the other two.)  SD files tidied.
This time with th heater set correctly...
Bug in Z probing (the Move class had no function to return the number of probe points) fixed.
Various bits of file tidying...
Corrected heater flag in Platform.h for Duet v0.6 (wrong in previous commit...)
Snowman added to G Codes...
Snowman tested...
M82 changed so that it reports steps/mm when given no arguments.
This time with correct version number and date...
Merge remote-tracking branch 'upstream/duet' into duet
Function added to set hypotenuse lengths for multi-axis steps.  These were previously computed on initialisation, but are now re-done after every M92.
Dud temperature count now has to reach 6 (about a second) before a heater trips out (Ian's request).  Also heater reset M code (M562) added.  Use that with great caution.
Bug where by selecting an already selected extruder did not reply (eg "ok" to Pronterface) fixed.
Default steps/mm set for new pulleys.
Build volume made less conservative (now 220x200x200).
