Updated for new game version
- Merged with changes to BP_BuildSystem_v2
- Sorted Argossean DLC buildables into proper places in the menu

- Added checkbox to build menu for toggling free build mode (same as Ctrl+Alt+Shift+F10)
- Added notification when free build mode is toggled

More fixes
- Placed things should now have inventories when appropriate (such as chests)
- Picking up things should now give you the proper item
- Undid some earlier fixes that seemed to cause worse problems than they solved

Attempt to fix reported issue. Could not reproduce these, so unsure if fixes work.
- Should no longer double place building pieces
- Should now prevent the place building input from reaching character and causing it to attack

Added ability to spawn items by holding shift when clicking.

Added several items that were missing from the building list. Also added support for items added by mods.

Make the mod only usable by admins
