Twit 02 Retrieve user twitter home stream

Creates a generic parser and requester. Performing a request against the REST api now requires the correct pair. 

Example:
To request the twitter android dev stream, the request requires the TwitterObjectRequester (Twitter responds with a JsonObject) and the TweetsHashTagParser to parse the Json object.


OH BOY this class `Manager`? try to avoid using generic names like Manager & Helper. Try to find a more specific name, if you can't it means your class is probably doing too many things and should be split into smaller & more specific classes
