Fixed Async Functionality on all Android Devices

Previously, the twitter fetches/gets only worked on Android 2.3 - 3.0
but not Android 4.0.  After much research, the problem turned out to be
that Android 4.0 requires network calls on a different thread so that it
does not block the execution of the main android thread.  This is the
workaround for it.  Twitter functionality is completely integrated.
Node.js server is not used at all right now, however, future plans may
be to add that server as a backup/ history log for various reasons.
