	Things to note:
	1. This function is basically the KinematicBody2D function ported over.
	2. The 'travel' variable and stuff relating to it exists more or less for this function's sake.
	3. Someone is going to have to document this, so here's an example for them:
	vel = move_and_slide(vel, Vector3(0, 1, 0), Vector3(0, -1, 0), 0.1);
	Very useful for FPS controllers so long as you control horizontal motion properly - even for Quake-style AABB colliders.
	The slope stop system is... rather weird, and it's correct operation depends on what scale your game is built on,
	 but as far as I can tell in theory it's suppposed to be a way of turning impassable slopes into invisible walls.
	It can also be a pain, since there's a better-known way of defining such things: "let gravity do the work".
	If you don't like it, set it to positive infinity.
	4. Might be a bug somewhere else in physics: When there are two CollisionShape nodes with a shared Shape, only one is considered, I think.
	   Test this further.
