avoid animeditor errors, don't show pac anims

don't show balanim part animations in animeditor and prevent multiple
animeditor errors regarding uninitialized variables
clean up old comments, no local file loading

local file loading isn't feasible since pac parts run on every client
and not every client will have the same files.

aside from that I'm just cleaning comments and variable names up
internally so that this is in the same place as patch-1.
