Godot is a pain with source control and sometimes you've just gotta have
a trash commit. This is it.

This reverts commit f41676c672.

I misunderstood the way the camera projections work, and I'm better off
using the original raycasting strategy.

And Camera.project_ray_normal. This is much better

Also, levels now inherit a level object

Hero 0 speeds up especially quickly!

Hero 0: Remove cursor, allow wallriding (enable collision detection)

Hero 2: Move RepelHUD to center, ignore self with Area (gravity)

Accidentally put it in the wrong place before

In multiplayer, if there is only one hero 1, it is ok, but with more
than one, one hero 1 cannot place walls.

This reverts commit 22cf954991.

While on wall, if you press jump, you leap up and away from the wall

If you do so immediately after leaving the wall (<tolerance=.150s), it
still works

There however were some bugs that came with this, so I'm switching to
master to explore this.
