better stats for urlBorg

urlBorg lets users see more detailed stats now.

There are many ways to access the click stats:

1. Click the "more info" link at the bottom of any "preview page"
2. Login to your account and click the short URL on any of the "created" or "clicked" links.
3. append /i at the end of a short url. ex ub0.cc/6/0h/i

The graphs are created using the Google Chart API and IMHO the look quite nice :-)
