Bug 248239 - Change standards mode height calculations for table cells to use content-box sizing rather than border-box sizing by default (and to honor -moz-box-sizing, which we do not do in quirks mode). Also remove -moz-box-sizing: border-box from default style for caption element (all modes). r=dbaron
