Package Management WiP
#ADD: Package Management should now be partly operational. Upon startup, all missing packages will be automatically installed.
#ADD: DualityEditor is now able to perform updates on DualityUpdater. That way, every single file is now self-updatable.
#CHANGE: Removed unnecessary references from ProcessingBigTaskDialog to other editor classes.
#CHANGE: Remoed lazy-verify from Package Management and replaced with a verify-all on startup.
#FIX: Fixed DualityUpdater crash when attempting to copy a file to a non-existent directory.
