I thought about it, but since even if it is in base_properties there
is still a lot of work getting it into each object::properties'
get/set methods, I decided to do alittle more work and add it to each
object.
Maybe we should change this somehow --
How about making each object::properties' get/set methods call
base_property::get/set after taking care of all the object's
properties, at the end, which should take care of all the properties
in base_properties?
