- fixed the GRBL_laser preprocessor such that it does not have a Z move at the end of the job due of the fact that this preprocessor has moves only in the X-Y plane

- in Milling Plugin made sure the preprocessors that have the `laser_z` in the name (case insensitive) have the ability to change the Z height at the end of the job (through End_Z parameter)
