- made sure that the right tools go only to the intended use, in Tools Database otherwise an error status message is created and Tools DB is closed on adding a wrong tool
- fixed the usage for Tools Database in Unix-like OS's
- done some modest refactoring
- fixed the Search and Add feature in Geometry Object UI
- fixed Paint, Isolation and NCC Tools such the translated comboboxes values are now stored as indexes instead of translated words as before
- in Geometry Object made sure that the widgets in the Tool Table gets populated regardless of encountering non-recognizable translated values
- in Paint Tool found a small bug and fixed it
- in Geometry UI finished a very basic way for the Polish feature (this will be upgraded in the future, for now is very rough)
- added some new GUI elements by subclassing some widgets for the dialog pop-ups
- in NCC Tool and Isolation Tool, pressing the shortcut key 'T' will bring the add new tool pop up in which now it is included the button to get the optimal diameter
- in Geometry UI and for Solderpaste Tool replaced the pop up window that is launched when using shortcut key with one that has the context menu translated
- some UI cleanup in the Geometry UI
- modified some strings and updated the translation strings
- in NCC Tool added a check for the validity of the used tools; its only informative
- in NCC Tool done some refactoring
- 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
- added a bilinear interpolation calculation class from: https://github.com/pmav99/interpolation
- in CNCJob UI Autolevelling: made sure that the grid can't have less than 2 rows and 2 columns when using the bilinear interpolation or 1 row and 1 column when using the Voronoi polygons
- in CNCJob UI Autolevelling - added a save dialog for the probing GCode
- added a new GUI element, a DoubleSlider
- in CNCJob UI Autolevelling - GRBL controller - Control: trying to add DoubleSlider + DoubleSpinner combo controls
- in CNCJob UI Autolevelling - added a mini gcode sender for the GRBL to be able to send the probing GCode and get the height map (I may make a small and light app for that so it does not need to have FlatCAM on the GCode sender PC)
- in CNCJob UI Autolevelling finished the probing GCode generation for MACH/LinuxCNC controllers; this GCode can also be viewed
- 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
- replaced some icons in the app
- in Code Editor, when changing text, the Save Code button will change color (text and icon) to red and after save it will revert the color to the default one
- in Code Editor some methods rework
