* --boost option is added to gettext_make_pot script to recognize Boost format strings.
* New script gettext_merge_po_with_pot is added to merging new lines from POT to current PO
* --check-format option is added to gettext_po_to_mo script to check language dependent format strings during generation MO from PO.
* POT is updated and all PO files are merged with it. So, community can just load needed PO file and continue in translation.
* ExtruderSequenceDialog: Added messed localization markers
* GUI_ObjectList code refactoring:
The MenuFactory structure contains functions related to the context menu and bitmaps used to different volume types.
The SettingsFactory structure contains functions to getting overridden options, its bundles and bitmaps used to setting categories.
Fixed bugs/crashes:
1. Add object -> Add Settings from 3D scene -> Right click on object => Part's Settings list instead of object's
(Same behavior if something else but Object is selected in ObjectList)
2. Add settings to the part -> Change part type to the "Support Blocker/Enforcer" -> Settings disappears (it's OK) but =>
Save Project -> Open project => Support Blocker/Enforcer has a settings
3. Add part for object -> Change type of part -> Change monitor DPI -> old type icon appears
4. Select all instances in ObjectList -> Context menu in 3D scene -> Add Settings -> Select some category -> Crash
* ObjectLayers: Fixed a crash on re-scaling, when some layer range is selected
* Fixed OSX build
* Added menu item "Split to Objects" for multipart objects
+ Fixed bug: Add 2 parts,
Add some settings for one part
Delete part without settings => Single part object without settings, but settings are applied for the object.
+ Next refactoring: use same menu for Plater and ObjectList
+ Fixed translation for the "Extruder n" category on the Printer Settings Tab
+ Fixed a crash, when scrolling inside Search imGui with some localization (e.t. Russion)
Implemented try/catch blocks for Slic3r exceptions and std::exceptions
with GUI error reporting. This is extremely important to report
corruption of PrusaSlicer.ini.
