Allows overwriting things without complaining

13:11 < mythmon> the slug variable on content pages needs to be unique.
13:12 < mythmon> so you are confusing wok and it is overwriting pages on disk.
13:12 < edunham> it didn't yell at me when it got confused, though

I wanted to create an issue related to the same subject. It is quite easy, when the site grows, to have two identical slugs, in different categories perhaps. This is not a problem anywhere but in the slugs dictionnary.

If slugs must be unique, a warning should be written when a key is overriden during the slugs dictionnary build, the way orphans are already detected. And it should be written with a big and red font in documentation. :)

But perhaps the pages could be stored with a diffrent key, like their URL, their path, or a tuple with their slug and category?
