Syntax Highlight Code Blocks

Some blogs/websites just put snippets of code inside of a pre > code block without syntax highlighting. This is alright, but for developers reading the code, it would be helpful if it actually included syntax highlighting. This extension, on activation via the context menu, finds all pre > code blocks an highlights them with highlight.js (https://highlightjs.org/).
