uiFaces 2

I've finally taken some time to address a few problems with uiFaces.com, namely that users cannot add themselves. Here is the latest and greatest:

- Users can add themselves
- The width of the entire container can be expanded
- There are more gradients
- There is an authorized section that lists individuals who are OK with their face being used as example data on live products (not just mockups)
- There are more bugs than ever before!

Feedback is very welcome.
