* 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
Implemented try/catch blocks for Slic3r exceptions and std::exceptions
with GUI error reporting. This is extremely important to report
corruption of PrusaSlicer.ini.
Introduced a new localization macro L_CONTEXT(string, context)
to define context dependent translations.
The only strings - "Top" and "Bottom" were already using context, but
until now the context had to be added to the PrusaSlicer.pot file
manually, while the context is being generated automatically now.
