Fixed a bug where left hand tool would not collide with Autumn zombies.

Left / right block are replaced with an upper cut (not the best animation)

Grab is a bit stronger and more reliable (especially when throwing)

Refactoring

Tool grabbing times out (no more swinging around not being able to grab properly)

Added axe

Removed jump in the air removed some unnecessary files.

Added tools (hammer and sword)

Added headlights

Removed crowd surfing: autumn zombies are ignored as stuff to step on.

A bit better first person control: if the mouse doesn't move then the orientation of the mech won't follow the camera.
