Admin Crate Update

Put simply, there are 3 main changes I did to each of the crate .sqf files:

* Added missing items to each crate
* Commented out the Hint and replaced it with the on-screen cutText (a lot of servers are using Debug Monitors that overpower these small hints)
* Added a 5-minute despawn timer to each crate (300 seconds)

Known issues:
* Hatchets and Crowbars spawn with 0 "ammo". I have no idea how to fix this.
* There's still a few dozen weapons missing from the weapons crate, but I don't see a real need to have every single weapon in the crate.
