Add Mozilla vendor prefix to the resource-detail css box-sizing property

This is to fix the resource detail page on FF v27
Maybe we can add `-webkit-box-sizing: border-box;` as well?

**Support**
Chrome (any): box-sizing
Opera 8.5+: box-sizing
Firefox (any): -moz-box-sizing
Safari 3: -webkit-box-sizing (unprefixed in 5.1+ versions)
IE8+: box-sizing
