added a trivial doctype (IE complained without it), but that caused a
gap to appear between the puzzle and the status bar, so I tinkered a
bit more and ended up removing the <table> completely (no great loss)
as well as adding display:block to the canvas and explicitly setting
the width of not only the status bar div but also its parent div.
Meanwhile, I'm putting the "px" on the end of a lot of properties I
set from JS, because IE complains about that too if I don't.
