Fixed object_name usage.

The object_name attribute was used as both an identifier and a
label which sometimes require different values (e.g. hbacrule
vs. HBAC rule). The code that uses object_name as an identifier
has been changed to use the 'name' attribute instead. The values
of the object_name attribute have been fixed to become proper
labels.
