Parse hyperlinked local MD files

[manigohan]

Describe the feature
Have hyperlinked files be also parsed into HTML

Why is this feature necessary?
Having this would mean anyone writing their website in pure markdown (and use marked) have seamless writing.

[Proof](proof.md)

Describe alternatives you've considered
Hyperlink the HTML file in markdown (e.g below)

[Hello](hello.html)

This isn't something marked can do. This will need to be done on the server. You can link to *.md files now but the server will serve them as text instead of HTML which the browser needs to know how to render things.

This would be a cool feature but will have to come from some other server software.
