Machinima Tools

I've been trying to make filming tools for myself so that I can quickly work with AI characters and objects while making machinima. 

I got tired of characters wandering off, spinning around, stretching and swaying so I've combined 2 of my other mod ideas into this one. 

I also needed a way to protect AI characters and vehicles from getting shot or blown up.

I'll see what else I can add, but for now you can:
- disable AI on a unit or a group of units
- disable idle animations on a unit or group of units
- make units invincible
- make vehicles invincible (tires still take damage, engine limitation)
