How to setup turrets and their limitations.

A complete mess of a video about turrets, dual turrets, limitations (can't limit rotations!) and stuff that's sort of related to turrets without going too far off topic. Weapons will need their own video. So will OCL's and OverlordContain modules.

This is really how to set up basic turrets. How dual turrets work and why they're rather useless. Adding some existing weapons and how things like ballistic missiles (with visible missiles) work.
