Add @viewport (inc -o-/-ms-) to syntax highlighter

Changes:
* support @viewport at-rules
* add min/max/user-zoom to property list
* add portrait and landscape to property value list

Currently I’m just using the property list for valid descriptors within the viewport at-rule, as that is what the file is also doing for font-face at-rule. Ideally they'd be split out to only accept the valid descriptors in the future.
