Highlight.js: Add Vue Single File Component (.vue) highlighting.

[sustained]

It shouldn't be too difficult to add since a Vue SFC basically looks like this:

<template>
VALID HTML HERE
</template>

<script>
VALID JAVASCRIPT HERE
</script>

<style>
VALID CSS HERE
</style>

The only thing to note would be that you can do e.g. <script lang="ts"> and <style lang="scss"> and such.
