Title: Sass compile of _reveal.scss results in empty z-index property

When compiled, you get z-index property that has no value. This is a problem if you have use something like Uncss in your build process to remove unused CSS. Also fixes a typo.

This fix simply gives the property a value of 'auto' rather than nothing at all.
