Fixed New {Thread,Post} buttons.
Aesthetics of post creation.

You can now click New {Thread,Post} and have correct dialogs show up.

TODOs:
    static-content/index.xhtml
        Load JQuery 1.x.x for IE, 2.x.x for a real browser.
    static-content/main.js
        Add actual functionality to the above. (Right now, the buttons are just "dummies").
        JQuery CDN fallbacks (Google's libhosting?)
        momentjs for dates, not ms after epoch.
