Redesigned the layout of gallery items so that text in a 'cell' cannot overflow into the cell below it.  Generally visually improve the layout of gallery items.  Interesting software development lesson in all of this (about accepted wisdom of not using tables to express html structure), but won't bore you with the details.

Also redesigned checkout process so initial checkout page is hopefully more intuitive.  More suggestions here welcome.

Finally, fixed an annoying IE9 bug relating to browser compatibility.
