Express 3

I've updated a few things:

* Express 3
* a later version of Jade
* newer versions of all dependencies
* a minor log message

I was going to change the version to 0.1.0 (from 0.0.0) but I figured this isn't in npm anyway, so doesn't really matter.

Can @ozten or @fmarier or anyone else review and pick apart this stuff - or just pull. :)

Cheers,
Andy
