Title: Added a PageBoxSize rule for restricting the dimensions of a box

Also allows an array of possible box sizes, failing if it matches none of them.

The PageBoxWidth and PageBoxHeight rules are arguably redundant, unless they're being used individually. PageBoxSize doesn't support restricting only one of width or height.
