Updated jQuery Equalize.js to add option for "margin" to be true or false (false being default). This takes the bottom margin of the last child of the element(s) being equalized and adds that to the resulting height (simply using outerHeight isn't sufficient as that doesn't take the margin of children elements into account). Useful when there's …

        children    = false,
