Improved styling of weapons table (although during editmode it increases
the sheet's width, but nothing else)
Added an image to the footer to spruce it up a little (taken from Ex3
book)
Code developed at http://jsfiddle.net/Lithl/jovd7L7s/
This implementation of Storyteller System traits is superior to the one
previously used on this sheet and developed for the 2e sheet in that it
permits higher values without taking up additional space. On the other
hand, it also requires using images to display the values.
