Markdown (.md) preview support

[Andrew Morrison]

Is it possible to consider adding a rich preview for markdown files? Maybe covering the   CommonMark Spec or the GitHub Flavored Markdown Spec.

It could be an option to just pipe the file contents in to something like this:  whistyun/MdXaml: Markdown for WPF - alternate version of Markdown.Xaml or similar.

Converting to flowdocument is an interesting approach. I'll make a note to check how it works and if it can also do other syntax highlighting

Awesome, many thanks. Really enjoying the app - it's a big productivity booster!
