Use Punch to build the site

Last weekend, out of boredom I turned WeBuild.sg into a Punch site. But forgot to send it your way :)

To try, 
* clone this repo
* `npm install`
* then run `punch s`
* go to `localhost:9009` on the browser.

I moved the events list into `contents/index.json`.
I can imagine writing a helper to grab the GitHub repos also, but didn't stab on it.

Anyway, there are few issues:
* Your lovely CSS3 animation doesn't work :( Seems libsass (which is used by node) has some issues in parsing styling rules with @-. Have to figure a workaround.
* It seemed you were wrapping <p> tags (block elements) inside an <a> tag (inline element), which is invalid markup. So I fixed it, but it borked the styling.

If you like to use it, we can sit together in a weekend to iron out the remaining issues (and add more awesome sauce).
