Box2D - wrong method implementation

Hi Brucey

I finally found some time to pursue my project ^^

There is a small mistake in the example test.bmx

ContactListener Type implement the remove() Method whereas it should be removed() according to the box2d.bmx
This is why removed contact points never process.

Note that in the box2d documentation remove() is the right one ;)

So how things going in the UK ? :D
