Notifications for custom meteor method calling

I don't know exactly how to test this...  but basically, I'm keeping track of the methodIds when specified, and checking for them first thing in responses, as the response data can be anything from an `NSDictionary` to a `BOOL`...  so want to make sure we handle it first...  and then I'm calling `response_XXX` with the data. 

Feel free to comment if you have any recommendations on a better way to do it...  thanks!
