Revamped how some of the method names work / are called in APIs. call/callUncached instead of less specific get/callAPI. Fixed oatuh_client to properly return error information from the API instead of throwing it in a string.

Started modifying oauth_client to be BigTree'd so that it's more maintainable. Gave up temporarily.
