URL exceptions

The module is very nice but it should accept some exceptions. For example with my module ( http://drupal.org/project/webdav ), ending slash SHOULD NOT be removed as it is part of WebDAV RFC compliance.

I made a quick patch adding a settings page to your module in order to add some URL exceptions. This is a quick way for doing this. Perhaps a better solution is to think about some kind of URL API with an hooking system in order for other modules to play nicely with yours.
