v3.0.0

• BC Break: The signature of useResource has changed, but only if you were
  passing options. If you called useResource(options) before, it must now
  be structured as useResource(resource, options) to be consistent with
  every other hook. See #63 for more information.
• In some cases when a React component passes a new resource as a string to
  useResource, the useResource might return "undefined" for the resource,
  which can result in a white screen of death.
  This one was a bit of a doozy, check the PR for more information: #67
• Remove an unneeded initial render in useCollection.
