 - added key shortcuts for Enable Plots, Disable Plots and Disable other plots functions (Alt+1, Alt+2, Alt+3)
 - hidden the snap magnet entry and snap magnet toggle from the main view; they are now active only in Editor Mode
 - updated the camlib.CNCJob.scale() function so now the GCode is scaled also (quite a HACK :( it will need to be replaced at some point)). Units change work now on the GCODE also.
