Known bugs/issues in this release:

* Currently, the RPC interface is a flat one. Extending the interface to be
  object oriented with a session class and a list class should at least be
  considered. (needs fixed dynamic objects in gnue-common's RPC library)

* Generated forms should show a normal entry with a search dialog instead of a
  dropdown when the referenced class has a property tagged with search="0".
  This way referenced classes with many records could be handled. (has to be
  implemented in gnue-forms first)

* When an exception happens in OnValidate, gnue-forms doesn't move to the
  record causing the exception, basically because OnValidate happens at commit
  time and not at store time. Not sure what would be the best way to handle
  this.
