added some tests to verify that the actual return values were matching the expected values
fixed a bug where margin/padding css weren't returning anything, same with backgroundPosition
I switched it from $.style to use $.css, but only because $.style wasn't working when used this way ( $.style(elem, name ). I wasn't sure which was more "low level" and which was preferred, but switched it just to get the tests passing and the cssHooks to actually return something.
