Basic setuptools support

This is a very basic setup.py to create an installable package. I can run reclass -h after installing but I've not checked anything else. There might be issue with locating things relative to the main module and I've not looked at the adapters at all.

It's best to work in a virtualenv for all of this...

To run tests:
python setup.py nosetests

To install from source:
python setup.py install

To build a source package:
python setup.py sdist

This can be pip installed and can be uploaded to pypi if you set it up and add more details to setup.py.
