Patch doesn't work when method to patch called from dict.

[GoogleCodeExporter]

What steps will reproduce the problem?
Run foo.py you'll find that when call_method_normally patching works but when 
call_method_from_dict the patch doesn't work. Not sure if it's a bug or a 
feature :-)

What version of the product are you using? On what operating system?
mock 0.7.2 osx

What is happening here (with the case that doesn't work) is that you are 
putting a method object into a dictionary. Then your "call_method_from_dict" 
fetches the object back out of the dictionary and calls it.

patch works by overriding name lookup (with the patch in place looking up the 
method "dummy_method" returns the mock). With "call_method_from_dict" the 
*name* "dummy_method" is never looked up, the object is fetched out of the 
dictionary.

You could use patch.dict to replace the method in the dictionary instead.
