Support for fast-forwarding with Cruft

[NordsofMorrow]

Hi,

This looks like a neat offshoot of cookiecutter! I'm wondering if you would consider integrating the capabilities of cruft into the ppw package?

cruft works by fast-forwarding projects from cookiecutter templates to reflect upstream changes in the template, i.e.: if the boilerplate has advanced and added features, cruft will apply those changes (to the best of its ability; will generate diff files otherwise).

A feature based on this would be a neat way of differentiating/empowering ppw (e.g. $ ppw fast-forward <local-clone>).

Thanks for sharing 'cruft'. I'm not familiar with cruft but I'll do some homework and get back to you.
