Physics Debug drawing enabled, physics objects draw in line with their scene2D counterparts,
jumping and moving left and right added.
More refinements, attempting to get away from scene2D, I figure I can just use it
for rendering and only link the player object to the inputMultiplexer.
also turned off physics debug rendering.
Feeling uninspired at this point, I guess I will just refine the physics geometry tommorow and the jump a bit more.
might do a titile screen too, just for completeness.
More ignores because of the HTML target generating a lot of cruft.
