Known bugs/issues in this release:

* GNUe_ClassRepository.gfd can not be used to create new classes and
  properties.  They just don't get saved.

* gnue-common's gnue-scripter doesn't support boolean type, so the sample
  .gsd's can't be processed with gnue-scripter.  gnue-common/utils/gsd2sql has
  to be used.

* .gsd's define the datatype "timestamp", AppServer uses "datetime".  IMHO
  "datetime" is the more logical name, so this should be added to the .gsd
  definition at least as an alias.

* gnue-forms doesn't support format masks for date/time fields, so the time and
  datetime fields in the samples can't be used with gnue-forms

* gnue-common's appserver dbdriver requests the list of types each time a query
  is done.  Actually it should be enough to request it once the form is opened.

* gnue-common's appserver dbdriver does a query with an impossible condition to
  create an empty result set.  This causes superflous RPC calls to AppServer.
  It should be possible for gnue-common to create an empty result set without
  doing a query at all.

* There is no way for the user to access the functionality in SchemaSupport.py
  (export class definitions into a .gsd file)
