untested commit of: updates to call urls, added static checking in rate limiting, and added match and matchhistory calls.
Added public variable for if you want to return json_decode()
tested my changes (seems to work), changed public class variable decode to static constant called DECODE_ENABLED, for continuity. Also changed the urls from http://prod... to http://{region}. I don't believe 'prod' works anymore.
