Major API break:

Major API break:
* Change all the ->get() to ->getAll()
  and all the ->show() to ->get()
  .. eg for User, Channel, etc.
* You now only create an API connection once, as it was always
  intended:
  $rpc = new UnrealIRCd\Connection(..)
* You can then either use the non-connection classes like this:
  $user = new User($rpc);
  $result = $user->getAll();
  Or simply use this style:
  $result = $rpc->user()->getAll();
* More breakage to come
