Provide a way to customize the class of child mocks without needing to implement _get_child_mock

[GoogleCodeExporter]

Attached is a patch implementing an arg to __init__ for all mocks that the 
default _get_child_mock implementation can use to instantiate child mocks. This 
can be used, for example, when subclassing, if different configuration needs to 
be done on a parent mock than on child mocks. See the doc changes for a 
concrete example.

(Tests pass for me on tip under all interpreters I have installed, which are 
all but py24, py31 and jython).

Cheers.

So overriding _get_child_mock is the intended (and documented) way of doing 
this, but your way is easier - at the cost of a new keyword argument to the 
already-has-too-many-arguments Mock constructor.

This would have to be in mock 1.1, which would be released at the same time as 
Python 3.4 (although there will be early alphas).
