Collection of tweaks/fixes

[JBraunsmaJr]

• Added flag on vehicle spawn points to ignore spawn system. Forcing a vehicle to spawn. Useful for testing
• Override for wrench added. It no longer requires supplies or maintenance area. Can do all repairs in the field.

• 8 Chance for weapon to have magazine implemented. - this is configurable

• Magazines spawn with random ammo counts - this is configurable
• Simplified saving/loading loot crates. Utilize global catalog to help figure out what can be saved, eliminating things such as canteens/suspenders/handguards being grabbed.
• Partially fixed player crate user info.
• AI Wander system implemented #5
• AI spawn with randomized loot. This system is based on conf files which indicate what to spawn, and the chance for it to spawn. Since AI have randomized weapons, this increases player options. AK's were commonplace thanks to AI so there was no drive to utilize other platforms.

Play tested with 4 players.

• Packing works for the most part
• AI Wander system definitely works and created some interesting gameplay at night. Also, in part due to fixing the vicinity logic.
• Random AI loot is not actually utilized right now. There's a duplication bug noted in #19 that needs to be addressed before incorporating it into the published version.
