Improved 3D Simulator

• F11 switches between fullscreen, fullscreen without NC and normal mode.
• Spacebar toggles play/stop for simulation.
• Simulation can be repeated in an infinite loop with new checkbox ‘repeat’.
• Support for executing multiple movements on a single line of NC code in the left pane. The move commands are grouped as usual with SIM-INFOTEXT, but empty string to this function is not a visible line in the pane.
