Initial draft support CSS for Markdown Preview - #6662

Well, so far for whatever reason Markdown files used two MIME_TYPE-s text/x-markdown-nb and text/x-markdown probably that was an oversight from the past days.

That made it possible to add the Plain text spellchecking support enabled for these files. it would be good to ignore spell checking in fenced texts, but that obviously needs more work. This addresses #6653

How is it possible to have 2 different mimetypes for the same file extension?

I think the bug is here: https://github.com/lkishalmi/netbeans/blob/c3dc5eb35cd382ac663db24ea9b79fcc0c725851/ide/markdown/src/org/netbeans/modules/markdown/MarkdownDataObject.java#L112

Where the DataObject which is addigned from the Resolver to the MIME text/x-markdown-nb registers an editor with the MIME text/x-markdown. That's being fixed in this PR.
