Updated Crate Menu to increase clarity, ease of use, and personalization:

* Removed Last Stand, Medical, Money, Repair, Skins, and Tools crates.
* Replaced above crates with a single "Items Crate".
* Added "(Most) Weapons Crate" for users who don't want to scroll through the massive All Weapons/Items Crate to find a weapon.
* Added CRATE_TEMPLATE.sqf as a baseline for users who want to make their own crates.
