Beginning re-write after hackathon. Not function
Can now put and retrieve users from the database

There are still hard-coded values, but at least the HTTP request doesn't
throw an error when you send a valid access token anymore.
Users are now properly read from and written to db

Very poor error handling for sending incorrect data types or tokens
being invalid.
Began writing unit tests for user.clj

Will come back and look into using Midje in the future
Tokens can now be created and dates are serialized

Serialization of dates to and from the database is now being handled
internally by Monger. Additionally, POST requests to create Tokens is
functional, however there is not very strong validation to make sure all
the required keys are present.
Can now retrieve tokens, and properly check for expired ones
Added token deletion
Fixed a couple compile bugs, added get-machines
Added creating/deleting machines and updating tokens

Also updated versions for a couple dependencies to reflect recent
releases.
Pre-removal of compojure-api
Stripped out compojure-api and added get-file
