Markdown Reader HTML Export

This extension depends on another extension [`md-reader`](https://github.com/md-reader/md-reader) on [chrome store](https://chromewebstore.google.com/detail/markdown-reader/medapdbncneneejhbgcjceippjlfkmkg). This gives you a green `Export HTML` button on bottom-right of the raw Markdown page which is rendered by [`md-reader`](https://github.com/md-reader/md-reader) in your browser. It gives you the functionality to export the rendered page to a HTML file which contains the [md-reader theme](https://github.com/md-reader/theme). Though, due to my knowledge limitation, this extension does not include the side panel which [`md-reader`](https://github.com/md-reader/md-reader) renders.
