jsonpatch.compare should not modify the mirror object

[alex3683]

I totally understand that jsonpatch.generate modifies the objects it watches to always only detect most recent changes (as discussed in #18 ) of an object. In my opinion this should not be the case for jsonpatch.compare as I explicitly use this method with objects that are not under control of jsonpatch observers. Thus modification of these objects should be under my control as well.

Pull request with improved performance was merged to master branch. You can use it now or wait for numbered release 0.5.0 (should be soon)
