adapted cover controller

An unofficial topdown version of Invector cover controller.

Basically, I Frankensteined the original elements of the top-down and the new cover controller.

No code was changed!

However, "Playmaker" was used to help with turning the player if any cover was available. 

The simple melee AI is used for all the zombies and "playmaker" is used to detect a specific AI is dead and activate the end screen.

"playmaker" is used to show or hide the mouse when the Inventory is displayed.

Controls:

Right mouse button to aim and turn.

Left mouse to shoot.

W, A, S, D to move, but an Xbox joystick should also work "maybe?"

Inventory opens and closes by pressing the I key.
