Digibug simplification cleanup. Upgrade digibug module to version 2.

1) Simplify the admin settings page to what most of our users
   want. Eliminate basic_ and default_ ids.  We just have company_id
   and default_id.  Advanced users can use advanced settings for now.

2) Fix security in print_photos (didn't get it right in my last commit)

3) Use the regular thumb and full urls if the images are publicly
   available to reduce load on the proxy.

4) Simplify proxy expiration code.

5) Eliminate all specialized styles from the admin theme.
