Fixed that "memento" keyrings were shown twice.
Credits to FalconX51 for reporting the bug! :)

Fixed that duplicate containers were shown for trunks that are always open, for example pickups.

- Added glovebox support
- Filter out seat / trailer (they already show containers)
- Show keyrings of zombies
- order the inventory buttons accordingly
- Prevent showing containers that are inside a container on the floor
(confusing I know... prevents crash)

Added support for (main) player inventory and fixed a trunk issue (was language dependent).
