Creates new zombie-world-mock.

In order to test acceptance without actually interacting with our world,
the world needed to be mocked out. The way this is done is a little
strange, but it is overriding the require cache so that we can control
what is returned by require('zombie-world'). It will still return the
production code, but it also has a mock tied to it. This mock allows for
overriding individual methods within the world so that we can control
what they do.

Also adds dependency on sinon, as that is our mocking library.
