Refactored CSS to encourage non-reuse of 'look-and-feel'; made a template HTML file

Split the CSS into multiple files, some meant to be reused, some obviously meant not to be.  Also made a template HTML file without all the actual content from the demo, and NOT linking to the "look and feel" bits of the CSS, so that people starting a new project have an easy time getting started, and an extra hurdle if they want to use the "look and feel" CSS.
