functionality. Just return false when using javascript:digibug_popup was not
enough from having the browser switch pages and show a page with the word false.
Using an event handler allows us to call event.preventDefault which cancels the
page switch.
1) Eliminate digibug_album.html
2) Get rid of the $(document).ready() in digibug.js and rename popUp() to
digibug_popup() then just make direct calls to digibug_popup() in the
menu urls.
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.
