added debug.js for running the widget on a desktop browser without development environment.
This makes the use of Nokia's Web Development Kit obsolete (didn't support WRT widgets anymore anyways). Note that debug.js is not distributed in the release package and is supposed to be used for development purposes only. Also keep in mind that debug.js only contains the bare essentials to make the ComingNext widget work. It is neither feature complete, nor bug free. It does get the job done though. :-)
