Fixed bug with previous checkin. Annotation drawing now stable.

- Minor change to listen template
- Fixed bug in drawabox where new boxes were not created with top/left statistics (drawn correctly, but the numbers were not included in the newBoc callback)
- Bug fixes for create/update/deleting annotations
- Added support for null dates in Annotation (rather than setting null's to Date.Min)
- No longer send an id field in the export object of an annotation if it is not defined
- Changed the preficate that determine the value for the isNew function to something more reasonable.
