This change implements floating point mod based on the algorithm used in LibM's fmod() implementation. To avoid taking a dependency on LibM from LibJS I reimplemented the formula in LibJS. I've incuded some of the example MDM test cases as well. This surfaced and issue handling NaN which I've fixed as well.
