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.


orly @dommerq :tongue: 

`public static final String ACTION_MY_STREAM_TWEETS = BuildConfig.PACKAGE_NAME + ".ACTION_MY_STREAM_TWEETS";`

but see comment in AndroidManifest too
