- added function to create lazy object reference by dao and id to application context
 (was useful to me for dto-to-model copy constructor)
- added function to create lazy collection references by dao, id and remote field
 (same like above)
- created optmistic locking capable entity (via version field)
- created BaseDao.initialFromCursor factory function to make coping with ID and version
  a little bit more flexible.
- bugfixed ModelBase field list naming
- bugfixed replaceBean method
- added support for optimistic locking, useful when multiple android clients are writing
  to one android master database.
