Rotatable ring markers

[brianmta]

I suggest adding the ability to rotate ring markers in the Map Editor. The main game does have rotated ring markers throughout, so I assume the implementation to be possible.

Example of rotated ring markers in the main game (time stamped): https://youtu.be/d5sH2XgIKmA?t=48425

Use this function to "rotate" ring marker.
