XCPANTS-1566: if .fyre.co is already int he NETWORK, remove it because we add it later.
XCPANTS-1556: dial down the url validation a bit to allow the {id} parameter.
Adds a `list_sites` method, fixes `_create_auth_token` to accept `display_name`, and adds a little documentation.
Remove debug print call and add some documentation to the create_auth_token function.
