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

Unfortunately, apply_impulse seems to have no effect right now. More
research is needed.

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

The camera setting got changed to default-enabled, when it should be
default-disabled.

This gives greater flexibility and stops some of those especially
annoying bugs

This is the real initial commit with all the code I have until now.

Networking: A server and 2 clients connect and then control their
players. This is still buggy. For example, every client controls the
/same/ player.

FPS controls: WSAD, Jump, and Look with mouse are all implemented (Taken
from Caliou's demo). This includes collisions.
