Improve scaleform transformation

[Zhincore]

This PR changes attached scaleforms in a way that:

• makes then rotate correctly on the Z axis (XY is still acting weird)
• improves relative positioning on all axis
• centers the scaleform relatively to the entity (needs improvement)
• scales them with correct aspect ratio so instead of the default (0.1, 0.05) it's (0.1, 0,1)

Problems found:

• often the scaleform "vibrates" and rotation glitches out for like one frame, but I haven't found a solution to that, probably networking?

EDIT: I assume scaleforms arent made to be moved often. Projecting on a flat prop instead works much better, but that's outside the scope of this project I think
