Changes

=== M190 M109 ===

M190 commands are MatterControl automatically converted to converts [http://reprap.org/wiki/G-code#M109 :_Set_Extruder_Temperature_and_Wait M109] commands to [http://reprap.org/wiki/G-code#M190:_Wait_for_bed_temperature_to_reach_target_temp M190] commands.

=== M140 M104 ===

M140 commands are MatterControl automatically converted to converts [http://reprap.org/wiki/G-code#M104 :_Set_Extruder_Temperature M104] commands to [http://reprap.org/wiki/G-code#M140:_Set_Bed_Temperature_.28Fast.29 M140] commands...

MatterControl accepts [http://reprap.org/wiki/G-code#G91:_Set_to_Relative_Positioning G91] commands for relative positioning, but instead of just allowing them straight through it interprets them as absolute coordinates and feeds those to the printer.

Certain printers do not accept [http://reprap.org/wiki/G-code#G0_.26_G1:_Move G0 ] as a valid command for movement, so MatterControl sends the more common [http://reprap.org/wiki/G-code#G0_.26_G1:_Move G1 ] command instead.
