removed the utility methods to get stuff from map[string]interface{} - better to use regular JSON decoding. made the json representation of game members look like the gameMemberState. added GameMember#is_owner() to the js. made the js look for nation ==  instead of == null since nation is a string.. made created GameMembers have email and owner be the base64 version of the user email so that it looks like we own them, AND the server can decode them without panicing. made the subscriptions to queries create proper slices.
