Title: Twitter export - now with twitpic

If the message link is a link to a picture then this picture will be uploaded to twitpic. (Only works with the alternate shortening mechanism)

It isn't implemented in the standard mechanism since that would be more complex to realize. (And I don't use that mechanism so I can't test it)
