- fixed some outstanding issues from the PyQt6 port
- PEP8 fixes
- minor fixes
- updated the saving of Preferences to update the self.options too: the `Apply` action will update the self.options but the `Save` action will save the updated preferences to the file on disk
- fixed CNCJob UI showing all tools in the Tools Table even when only some tools were selected for processing
- fixed the `drillcncjob` Tcl Command to work in the case of drilling a selection of tools instead of all, with toolchange inactive
- made sure that the `drillcncjob` and `cncjob` Tcl commands will use the `-las_power` parameter to set the laser power when using a preprocessor with `laser` in its name
- fixed crash when trying to do a `select all` and there are app Scripts present
- updated the `drillcncjob` Tcl command to make a script exit in case of an error
- updated the Tcl command `drillcncjob` to store the tool gcode and the parsed tool gcode in each tool data structure
- updated the Tcl command `drillcncjob` description and examples
- fixed Tcl command Isolate to not print messages on message bar in case it is run headless
- fixed Tcl command Copper Clear (NCC)
- fixed Tcl command Paint
- fixed partially the Excellon Editor to work with the new data structure
- fixed Excellon export to work with the new data structure
- fixed all transformations in the Excellon object attributes; still need to fix the App Tools that creates or use Exellon objects
- fixed the issue with factory_defaults being saved every time the app start
- fixed the preferences not being saved to a file when the Save button is pressed in Edit -> Preferences
- fixed and updated the Transform Tools in the Editors
- updated the Cncjob to use the 'endxy' parameter which dictates the x,y position at the end of the job
- now the Tcl commands Drillcncjob and Cncjob can use the toolchangexy and endxy parameters with or without parenthesis (but no spaces allowed)
- modified the Tcl command Cncjob such that if some of the parameters are not used then the default values will be used (set with set_sys)
- modified the Tcl command Drillcncjob to use the defaults when some of the parameters are not used
- removed the import of the whole FlatCAMApp file only for the usage of GracefulException
- remove the import of FlatCAMApp and used alternate ways
- optimized the imports in some files
- moved the Bookmarksmanager and ToolDB classes into their own files
- solved some bugs that were not so visible in the Editors and HPGL parser
- split the FlatCAMObj file into multiple files located in the flatcamObjects folder and renamed the contained classes with names more suggestive
- updated the Google Translation for the German language
- in Excellon UI removed the tools table column for Offset Z and used the UI form parameter
- updated the Excellon Editor to add for each tool a 'data' dictionary
- updated all FlatCAM tools to use the new confirmation message that show if the entered value is within range or outside
- 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
- added a new entry in Menu -> View -> Redraw All which is doing what the name says: redraw all loaded objects
- fixed issue where in TCl Shell the Windows paths were not understood due of backslash symbol understood as escape symbol instead of path separator
- made sure that in for the TclCommand cncjob and for the drillcncjob if one of the args is stated but no value then the value used will be the default one
- made available the TSA algorithm for drill path optimization when the used OS is 64bit. When used OS is 32bit the only available algorithm is TSA
