  Log Message:
  -----------
  Add preliminary activity state purging

The activity state is now intelligently purged (according to the
persistence level) at task restart. Tests up to model-impl seem to pass.

Work in progress: higher persistence levels are not yet used.

Other changes:
 - Added realization state property for the whole task tree.
 - Changed schema of TaskActivityStateType to make it more structured.
