Revision of DiffModule from Thu, 21/04/2005 - 6:47pm

I'm stil having some problems with the wiki formatting breaking, But i think I'll dump the diff as it is without applying filters.
It's in the unified diff format and not colored! It's inline diff, The underlined lines are new, The striked ones are deleted.
I gave the admins and mods the permission to access it until I fix all of the remaining things.
Todo:
* diff to previous/next/beginning.
* Admin interface to choose unified or inline diff.
* Find a way to highlight.
* Try to write the diff code instead of using pear.
