Added more gui features. Ad
ded some more functionality to the finder users tab, now can return list of users who are following
another user. Doesn't work with keywords yet though. The Tweet class had to be modified because user
s who didn't have a status message kept giving me a null pointer error so I had to add a try/catch a
nd set the 'message' field to 'none' if the user didn't have a status update.
