Feat:Adds Line Lock Module

[PoTheMagicDragon]

Description

An alternative to rotation lock. Instead of locking your rotation to a certain angle, it locks it towards a line. That way when you bump pigmen on the highway, you realign to the middle instead of getting pushed off to the side.

This comment explains the functionality pretty clearly

		//  When enabled we lock onto a straight "rail" and steer the camera down it:
		//
		//        lineOrigin ●─────────●──────────►  lineDirection (the way the rail points)
		//                            ╱ closestPoint (rail spot nearest you)
		//                    you ●──╯                → we aim a bit further down the rail
		//                                              (lookaheadPoint) so you curve back on
