[Opensim-dev] opensim 8392 breaks build of modularex

[Peter Quirk]

The following change in version 8392 to NHibernateManager causes build 
errors in Opensim.Data.NHibernateRexObjectData.
** Changed NHibernateManager.Save method name to Insert as it does Insert.

Three references to manager.Save(item) need to be changed to 
manager.Insert(item)
