Slugs must be unique within a schema

[tivac]

EDITED: This used to talk about unique names, now after #104 has landed it's all about unique slugs.

@kevinkace do we really want this? As discussed it doesn't necessarily solve the slug problem since these sluggify to the same thing.

I'm a title
Im a title

[kevinkace]

Indeed unique titles probably don't get us much.
Need some dependable way to find correct content from slug, just not sure what.

[tivac]

May be time to add slug as a built-in concept and ensure that those are unique (+ make them editable).

Bleh.

[tivac]

Slugs are now built-in after #104, so this should happen.
