scikit-bio 0.1.3: pre-alpha release

This is a minor update to the scikit-bio pre-alpha release. You can review our CHANGELOG.md for a description of the changes since 0.1.1.

Please keep in mind that scikit-bio is still a pre-alpha release and that major backwards-incompatible API changes can and will happen. That said, we're excited to have people start using scikit-bio. See our (awesome!) documentation if you're looking to get started with scikit-bio. If you have bug reports, features requests, or support requests, please post them on our issue tracker. Finally, be sure to check out our new website!

Some of the developers (@gregcaporaso, @ElBrogrammer, @adamrp and @ElDeveloper) will be attending SciPy 2014 this summer, and @gregcaporaso will be presenting on scikit-bio. Come find us if you're interested!
