Cleanup

The first commit in this pull request is a coding style change to urls.py (across all modules). I simply just moved the first parameter of the calls to the patterns() function to the first line. This makes them a little bit more readable and consistent with other django projects.

The other commits remove the search views from images and docs as these are no longer used anyway. They also clean up the index views for docs/images to make them easier to read (and easier to maintain).
