Updated to remove the dependancy on the regular expression-friendly
rename. The script now allows you to specify which files should be
renamed. It is now possible to 'test' the debranding process, to see
what changes will be made to each file before committing. A 'help' has
been created, showing how to operate the script. The script now runs
using '/usr/bin/env bash' rather than '/bin/sh', meaning it should now
work properly on Debian based distros as well as any others where 'sh' isn't a
symlink to 'bash'. The lists of scene and information tags are now in
alphabetical order, and I'll be attempting to keep them this way. A
number of bugs that would occasionally result in dataloss should be resolved now as they were caused by the rename tool that was being used. The script now only runs on writable files, and not directories, block devices, character devices or symlinks.
