- updated the 'Default_no_M6' preprocessor by removing the Tx command in the Toolchange section to make it compatible with GRBL controllers

- added a new preprocessor named 'Check_points' which is to be used to check if the PCB is well aligned in position (used by at least the Corners Tool)
- Tool Corners - added a new feature that creates a verification GCode by moving in the locations positions; modfied the UI a bit
- Drilling Tool - removed the mandatory Toolchange event added even if the Toolchange was not selected
- Excellon and Geometry objects no longer have the self.options dict overwritten with the application defaults
- Drilling Tool - first tool that benefit from using the object options instead of application defaults; this is useful if an object is recreated on project load
- Drilling Tool - fixed it to update the UI form also for common parameters on object change
