- added a way to terminate QThreads safely by waiting; should be much safer
- made sure that the ArgsThread class receive the signal to stop
- made sure that on application shutdown, all workers will quit before the actual exit
- applied the FCMessageBox GUI elements everywhere; there is still a hack in appTranslation file where I needed to re-implement the class due of some circular imports errors
- trying to separate the Preferences settings from App init and to make them dependent on the self.defaults dictionary
- updated the language strings from the source
- Drilling Tool - fixed missing feedrate code when the toolchange is Off
- AppTextEditor - working on syntax highlighting
- App - trying to speed up the new project creation
- Tcl Shell - Browser Edit - added Undo/Redo, Cut and Delete selection
- replace all the exec_() calls with exec() (except one situation in Tcl where I'm not sure of the effect)
- commented the ToolsDB class since it is not used currently
- some minor changes in the AppTextEditor.py file
- removed Hungarian language since it's looking like is no longer being translated
- made sure the the GUI settings are cleared on each new install
- added a new signal that is triggered by change in visibility for the Shell Dock and will change the status of the shell label in the status bar. In this way the label will really be changed each time the shell is toggled
- 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
