Extra changes to 0.1.5.2

- Fixed logging out issue
- Both Secondary and Primary mags will save. Sadly, primary mags can
only save IF you have your primary weapon out. If not, the primary mag
will not save. This is due to missing scripting commands and will be
fixed when they add one. Mags save across models but the same issue can
occur.
- Utilities should now be directly equippable right after spawning.
(Maps, compasses, etc).
- Added more security to removing items from zombies.
- Weapons in backpack won't duplicate and overwrite equipped weapons
anymore.
- Morphine fixed.
- Added Survival Med. Pack
