Try to ensure unique file names when collapsing subdirectories
Make the parse tree conform to the shr dom
Ignore "the" and "a" when sorting
Create a symlink directory of unseen films
Mark longer files more clearly
Get the position from the stats file, if possible.

This makes it easier to view the same files from different
machines.
Mark even more clearly the long files
Don't overwrite other text properties with the long-file marker
