Cool, thanks.

It took me some time to figure out how it works but you can add
Markdown as filetype by placing the attached markdown.properties file
into Scite's datadir ($prefix/share/scite) and edit
SciTEGlobal.properties, there are several places where you need to add
it, I just searched for YAML and replaced it with markdown :).
