- fixed bug in NCC Tool: after trying to add a tool already in the Tool Table when trying to change the Tool Type the GUI does not change

- final fix for app not quiting when running a script as argument, script that has the quit_flatcam Tcl command; fixed issue #360
- fixed issue #363. The Tcl command drillcncjob does not create tool cut, does not allow creation of gcode, it forces the usage of dwell and dwelltime parameters
