Updated the pomodoro timer

I've finally upgraded the pomodoro timer. List of updates:

• You can now open the applet in a pop-up window. See fourth tab on the top.
• Buttons instead of small links. (Thanks Sten, Johan)
• Fixed a bug that prevents new unplanned and urgent items beeing added after the last one has been moved up.)

If you are a pomodoro fan without a physical timer, -go ahead try it! You are encouraged to leave feedback on http://www.itlanddata.no/the-pomodoro-technique/feedback.html If you like it, you are also encouraged to give me a link back. (Thanks again, Johan.)
