Make it only show with status bar clock

If you looked at my comment on the last commit, In the screen shot the date is shown both with the clock and date. Now it will show in the status bar with the clock, and with the date only in the notification panel.

Also add checking if the date changed because this is how it looks with "Show before clock"

and it will continue until the original date disappears.

Can you check if the Id (2131230770) I used is the same for you ?
