Add markdown support for comments

[brady77]

Completely new possibilities arise from the "Comments" section! If you add styling with markdown to Comments I would be able to take notes directly. The HTML support is already there.

With markdown support I can imagine Geekmarks as my Personal Knowledge Base. I'll be happy to discuss the note-taking topic further (in a separate issue?). I tried many different note-taking apps. As far as I know non of them is so powerful and so minimalistic (at the same time) as yours "search-and-find" approach. Something org-mode offers (hierarchical tagging), but way more user-friendly and quick. Simply love Geekmarks!

Thanks for the suggestion!
