Update homepage in setup.py

[furrykef]

The setup.py file still lists http://launchpad.net/parsley as the project's homepage, which means PyPI does as well. I think it should point to this github page, since everything on the launchpad.net page is for 1.1 and earlier.

The launchpad.net page should also be updated to indicate that the project has moved. I nearly fell under the impression that parsely might be abandoned because PyPI only contains a link ot the old page and the old page's repository hasn't been updated in ages.

I noticed it too. I think it should be fixed.

The PyPI version doesn't work with python 3, either.
