- 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
- 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
- changes in Milling Plugin in the selection in the Tools Table
- some updates of milling data structure
- changes in handling the tool shape due of moving the parameter from the tool table in the tool parameters section
- Fixed the SolderPaste Plugin regarding the special designation 'SP' job type and 'DN' tool shape
- some fixes in the GCode Editor regarding the new changes in the data structure
- some changes in data tools structure ('tool_type' to ['data']['tools_mill_job_type])
- some strings changes
4.07.2021
- optimized the Milling Plugin preferences
- added more preferences for v-shape tools in the Milling Plugin Preferences
- deactivated the automatic disable of the Cut Z parameter when selecting a v-shape tool in Milling Plugin
- in Milling Plugin added some protections against receiving signals from widgets without objectName set
- in Milling Plugin made sure that the Custom offset field is displayed only when it is needed (selected from Offset Type combobox)
- added some requirements asked by vispy v0.7.0
- if the generated Gcode is empty then the app will know and will not create a CNCJob object
- modified the Tool Table in Milling Plugin: now the tool type parameter is part of the Tool parameters and no longer in the Tool Table
- working on a Kosy CNC machine preprocessor file
- made sure that old projects load but without the CNCjob objects which would have crashed the app due different data structures
- the FlatCAm Evo projects load now in succession, no longer on threads
- fixed the Tcl Command AlignDrillGrid
- fixed the Tcl COmmand Panelize, Excellon panelization section
- Fixed an issue in Tool Calibration export_excellon method call
- PEP8 corrections all over the app
- modified the Properties Tab for various FlatCAM objects preparing the move of Properties Tool data into the Properties Tab
- if the Properties tab is in focus (selected) when a new object is created then it is automatically selected therefore it's properties will be populated
- cleanup of the CNCJob UI; added a checkbox to signal if any append/prepend gcode was set in Preferences (unchecking it will override and disable the usage of the append/prepend GCode)
- the start Gcode is now stored in the CNCJob object attribute gc_start
- GCode Editor - finished adding the ability to select a row in the Tools table and select the related GCode
- by default now a new blank Geometry object created by FlatCAM is of type multigeo
- made sure that optimizations of lines when importing SVG or DXF as lines will not encounter polygons but only LinesStrings or LinearRings, otherwise having crashes
- fixed the import SVG and import DXF, when importing as Geometry to be imported as multigeo tool
- fixed the import SVG and import DXF, the source files will be saved as loaded into the source_file attribute of the resulting object (be it Geometry or Gerber)
