Title: Added ability to specify self text via the '/submit' url paramaters.

Example: `/submit?text=Example%20sefltext`

If no 'text' parameter is supplied the form's behaviour is as before.
If a 'text' parameter is supplied (and the subreddit allows text based submissions) the text tab will be selected and the usertext area pre-filled with the supplied data.
