Cookbooks Directory

:fork_and_knife: Starts to add cookbooks directory as seen [here](https://projects.invisionapp.com/share/FNPSQDDE#/screens/16696873). There are other things we'll want to eventually be able to order, filter, search on but those things are all captured by other stories. This is mostly a step in addressing #192 which it does except for most downloaded and followed as some additional work is required to get that information.
