Decorated function names are not preserved

[kumar303]

The @capturemock decorator returns a wrapped function without preserving the original name of the function. This interferes with test runners that run functions by discovery (e.g. Nose, py.test, unittest2).

The fix for this is to simply copy original_function.__name__ into the new function and as of 2.5 there is a builtin functools function for this called wraps. Attached is a basic patch with wraps showing how it works.

CaptureMock has its own bugtracker...

Many thanks for the patch, will try to integrate it in the next couple of days.

Integrated and added test.

Actually py.test, which I've mostly been using when not using TextTest, coped with this situation fine (wonder how) but at least nose didn't.
