Because of the new method, I don't know a better way to set the NSInteger from a string in the channel object.
Fixed the bad utf8 encoded json by going through all the bytes and if it's between 0 and 0x20 (32) then i'll just change it to a space (0x20)
Added "JsonHelper" so I don't have to repeat the code every time.
Added some if debug to those NSLog's
fixes #28
