Fix movement forward, backward, left, and right

[toivocat]

Movement was:

if Input.is_action_pressed("move_forward"):
	direction -= transform.basis.z
elif Input.is_action_pressed("move_backward"):
	direction += transform.basis.z
if Input.is_action_pressed("move_left"):
	direction -= transform.basis.x
elif Input.is_action_pressed("move_right"):
	direction += transform.basis.x

But needed to be:

if Input.is_action_pressed("move_forward"):
	direction += transform.basis.z
elif Input.is_action_pressed("move_backward"):
	direction -= transform.basis.z
if Input.is_action_pressed("move_left"):
	direction += transform.basis.x
elif Input.is_action_pressed("move_right"):
	direction -= transform.basis.x
