AI files that use globals instead of locals

[relent0r]

Describe the bug
While investigating a dead loop and looking for oddities I found a bunch of varaibles related to AI that are set as global instead of local. This could be causing issues with AI where they are sharing/modifying each others variables during games which would cause strange behavior.

I'll go through and look to fix the AI specific ones that I understand and consult others for ones that are not directly AI. The biggest culprits are the Sorian functions.
