Addons and Adjustments

- Fixed SurvivalPack spawning so it doesn't attempt to spawn ammo
- Added Scar L, Scar L Holo, Scar H CCO, Scar H CCO SD. The Holo and CCO
SD do NOT spawn with ammo. :) Just cause I'm evil.
- If the group menu is open, it should close if delete is pressed
(instead of reopening it).
