Change requirements to refer to a specific maker-py, version to 0.1.3.

Version 0.1.3 is what we've been referring to all along, so maybe it
should be 0.1.4. The maker-py commit is the one I -think- corresponds
to the specific version we want, it's when the version bump happens in
maker-py.
this needs to be

egg=maker_py-0.1.3
