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.


:x: deal with your exceptions, use simple Log (because we have control over it – can be enabled/disabled) or rethrow & deal with it somewhere else but never use `printStackTrace`
