Photohunt API

	Semi-formally, the JSON communicated will follow the following EBNF
	(https://en.wikipedia.org/wiki/Extended_Backus%E2%80%93Naur_form) grammar (note
	that this is only roughly EBNF):

	(* Valid error codes *)
	ERR_SUCCESS = 0 (* No error occurred *)
	ERR_UNSPEC = 1 (* Unspecified error. Message contains additional information *)
	ERR_NOTAUTH = 2 (* Authorization token invalid *)
	ERR_GAMEOVER = 3 (* Photohunt competition is over. No judged submissions allowed *)
	(* Additional error codes will be added during development *)
