* (reverse) sort albums. I did this because my album names all start by
a date, and I want the newest albums displayed first.
* Sift out files that aren't identifiable by ImageMagick or PIL so that
they aren't counted in the total number of pictures in the album.
* Changed path to match new Setup.py format
* Modified paths to work with new Setup.py format
* Changed PIL to use ImageMagick as backup, since it is slower but reads
more formats
* Changed setup paths so that they distinguish between the directory
structure as seen by the OS and as seen by the browser
