Migrations (#13)

This version adds database migrations. They run using a very, very simple custom-built system that can only migrate upwards. Hopefully these won't be necessary very often, but they should be useful when they are, such as in the next feature.

Pin Queue (#11)

Instead of doing all pinning operations while the client is hitting the appropriate endpoint, instead pins are now handled asynchronously by a queue that runs in the background. This means, among other things, that actually doing the pinning is no longer dependent on the client staying connected. Before this, if the client disconnected while the IPFS node was still trying to pin something, the pin would just fail completely. Not great for an HTTP API. Now that's not a problem anymore.
