RotateVector for Vector access

[Major Cooke]

This could be very useful for UI purposes. Or allowing vec2 and vec3 the Rotate() function with an angle for a parameter.

I second this.

Is it so performance critical that you can't write own function? It's trivial to convert TVector2<>::Rotated() to ZScript.

Actually, the bigger problem here is that these functions are still in Actor. They really should be part of the actual vector structs instead and then deprecated. But don't expect me to relax the conditions on the Actor variants.

Alright, yeah, too much disassembly for me to handle.
