Properties preserve and respect the PropertyDescription 'isMutable'

property. This setting prevents the WriteProperty predefined step from
changing the property value when isMutable is false. WriteProperty also
requires the selected property to already exist - they should be created
either during Item instantiation or using AddC2KObject.
LDAPPropertyManager prepends the Property name in its entries with ! if
they are non mutable.
Various places around the kernel that create properties now set the
mutable field.
Fixes #150
