make wrap_all more robust

[kurtbrose]

First: wrapping builtins (e.g. setattr from object) raises exceptions

        File "/services/shopkick_pylons/shopkick_pylons-current/py/lib/python2.6/site-packages/boltons/funcutils.py", line 488, in from_func
             'module': func.__module__,
        AttributeError: 'wrapper_descriptor' object has no attribute '__module__'

Probably the way to fix is to add a filter for hasattr('module').

Second: wrapping @staticmethod breaks because the descriptor protocol that elides off the self parameter gets "erased" in the wrapped function

A bunch of different ways to fix

Finally, it would be convenient if the skip function could take the object itself as well as the name in order to work-around these issues and any other unanticipated ones. (Maybe parameters similar to descriptor protocol get / set for the skip argument to wrap_all?
