Improvements with respect to PrusaSlicer 2.2.0-rc3

• A new "Draft shield" option has been added to produce a skirt as high as the highest printed object. (#2675)
• A free camera rotation is no more forced for a regular mouse when a 3DConnexion device is plugged in. If the camera up vector does not point up because the camera was rotated with the 3DConnexion mouse, the camera is newly aligned with the screen Y axis abruptly when touching the regular mouse and a constrained camera rotation mode is active. (#3816)
• Thumbnails for BIBO and LulzBot printers were added to installation wizard. We changed location of these thumbnails, they are newly stored inside the resources/profiles/VENDORNAME/ directory, and they should be named by the printermodel identifier suffixed with "_thumbnail.png".
• The plus button to add a new layer range modifier newly grays out if is not possible to insert a new layer range and the tooltip explains why.
• Updates to BIBO printe profiles by @photodude.
• Brazilian Portugese dictionaries updated, thanks @BoaImpressao3D.

Bugs fixed with respect to PrusaSlicer 2.2.0-rc3

• Full fan speed for gcode visualization was not shown as 100%, fix provided by @rongith. (#2922)
• Eject of a removable media did not handle fails properly. A message box is newly shown if eject fails.
• Windows specific: Detection of a 3DConnexion mouse has been refactored to not poll every 2 seconds, but to react to operating system notifications. This should resolve some peculiar freezes of the user interface. (#3424, #3515)
• Windows specific: Detection of external drives (SD cards, USB flash drives) newly reacts to operating system notifications, so it should react faster. Still some attach / detach events are not reported by Windows, therefore the disk devices are still enumerated every 2 seconds.
• Windows specific: The slicing service pops up error messages asynchronously. If a pop-up menu was tracked at the time the background service popped up the error message, the PrusaSlicer application was stuck. The error dialog is newly delayed until the pop-up menu closes. (#3660)
• Opening the File menu hang on enumerating the removable drives to update the "Eject" menu item. Also due to a bug in the wxWidgets UI library, the same happened when opening the "Extruders" submenu of an object pop-up menu. This issue has bee resolved by relying on the last known state instead of blocking. (#3279)
• The Wizard checkbox text "Remove user profiles - install from scratch" was changed to just "Remove user profiles" to indicate that this checkbox does nothing to system profiles. (#3761)
• Fixed a vase mode issue, where the infill layers were not recalculated correctly after the number of bottom layers were changed. (#3823)
• Removed a spurious "Unable to enumerate HID devices" console message indicating that no HID USB device was detected, which is likely fine. (#3828)
• Fixed mouse handling issue at the object list, which was a regression issue from PrusaSlicer 2.2.0-rc3 introduced when trying to fix #3802. (#3830, #3841)
• Fixed wizard issues regarding upgrade from PrusaSlicer 2.1.1 to 2.2.0: Most system presets were renamed for PrusaSlicer 2.2.0 by adding the "@" character to separate logical name from the full name of the profile, and this was not being taken into account by the installation wizard correctly. (#3835)
• Fixed installation wizard to always install at least one Filament or SLA material compatible with an installed printer model.
• The Prusa system profiles "Generic PETG" and "Prusa PETG" are now marked as renamed from "Generic PET" resp. "Prusa PET", so that when opening an old 3MF file, links to these system profiles are not lost.
