Create a front-end.
Add a timestamp column to the articles.

I forgot why it is needed, but I'm sure it will come in handy at some point...
Ignore some more stuff.
Include knockout.js for a fancier frontend.
Moving files around to an express namespace so that we can use other frameworks.
UX improvements in article list and edit article page.  Begin tags support.

- Make whole table row clickable when listing articles.
- Include "reset" and "back" (history back) buttons on article edit page.
- Add tags to database, show tags on article edit page.  (But there is no way to edit them, yet.)
Add navigation bar (ugly implementation) and improve tags support a little.
