[+][BUG] Disallow flipping/rotating of force-fields

[WillLem]

From ericderkovits on Discord:

I noticed the force fields can be rotated, inverted or flipped in the editor, thus making the force fields NOT work correctly. (ie flipping a left force field only flips the graphic but not the way it works, so a flipped left force graphic faces right but still acts as a left force field (Wrong), as the .ini file still says it acts whichever direction (left or right) even when the graphic is flipped.

I think force fields should NOT be allowed to be rotated, inverted or flipped just like the OWW's

Agreed. I'll fix this for the next update.
