Support line, start, and highlight parameters from SyntaxHighlight extension

[kuenzign]

The SyntaxHighlight MediaWiki extension (which this extension aims to provide an alternative to) supports the line parameter (with optional start parameter) for adding line numbers and the highlight parameter for emphasizing specific lines. It seems that base highlight.js does not allow these, but from a few quick Google searches, it appears that there are two plugins that add support and work together:

• Line numbers: https://github.com/wcoder/highlightjs-line-numbers.js/
• Line highlighting: https://github.com/TRSasasusu/highlightjs-highlight-lines.js
