Probing

For probing buttons that use subroutines if you name them probe_something_pb and replace something with the name of your choice. They will be disabled if the spindle block checkbox is not checked.

Add a QCheckBox named spindle_block_cb and if it is checked the spindle is set to 0 and off and any push button with an object name that starts with probe will be enabled.

Add a QPushButton named spindle_block_pb
