A simple one line fix to fix the positioning of the attribute dice size box due to the changes that Roll20 made. I had been working with the other collaborator before he too vanished. It's a small fix though and hopefully can be passed easily.
Changed the style of the Advantage menu to allow up to 12 Advantage and
Disadvantage. Also fixed a small bug where the Power Level for Boons in
the Actions section did not update correctly.
