18. $Item->Xxx("foo") does not go through PutColValue()!

Instead AUTOLOAD sets the specified property directly, maybe for performance
reasons, and PutColValue() is only used by DBIBackend.pm.

The consequence is that there is no way to take special action when a specific
property is modified. It is however still possible to detect whether a given
property was modified by overriding ResetModified(), saving its initial value
there and then comparing the current value to the saved one.
