0.8.8:

* Details Layout: Simpler, hierarchical layout. This allows 
  more complex layouts, and allows fields to appear more than 
  once on the same layout.
* Documentation: Added user manual, though it looks a 
  bit strange in yelp at the moment.
* Relationships:
  - Avoid crash when fields of differerent types are used in
  relationships.
  - Actually delete relationships when the delete button is pressed.
