scripts/create-recipe: Python improvements for create-recipe.

1. Added ability to parse .zip files.
2. Added optional automatic dependency resolving for python
   recipes(easy_install wrapper).
3. Fixed a few name/version bugs.

Give it a whirl by:
create-recipe -r https://launchpad.net/nova/folsom/2012.2.3/+download/nova-2012.2.3.tar.gz

Saves me some time unwinding python dependencies, and creating template recipes.
