wishlist: ability to patch class staticmethods and classmethods

I would like to be able to do the following:

------------------
import mocker

class O(object):
    @staticmethod
    def foo(a):
        return a

m = mocker.Mocker()
mO = m.patch(O)

mO.foo('x')
m.result('y')

m.replay()

assert O.foo('x') == 'y'
-----------------

I have actually tried to do it, expecting it to work, and I took some time to notice that it was not really supported.
