Ensure uniqueness of Rule Names within RplSet EVEN with respect to disabled rules [6034]
Bug Number: 6034
Release notes (y/n): Yes
For Release Nums: 7.2

Gnats 6034: Duplicating an inactive rule does not give the new rule a 
  unique name.

When duplicating a Rule, the new rule is given a name based on the original 
rule, with a unique number suffix.  That algorithm excluded both Disabled 
Rules and Disabled Rule Groups.  With this change, all Rules and Rule Groups 
are relevant when insuring Rule uniqueness within a given RplSet, including
disabled items.  This change is relevant also to editing the a Rule's name.

However, RuleSets saved with multiple Rules having the same name are loaded 
without errors or automatic rule name changes.  And, as before, if more than 
one such rule is enabled, an error is generated when the ruleset is validated 
(e.g. as part of starting a run).

In the past, a rationale for allowing multiple Rules within a Ruleset to have 
the same name (but with only one enabled at a time) was to allow 
experimentation of different versions of a rule.  Elimination of that 
possibility is substantially mitigated by ease with which references to a 
rule can optionally be updated when changing a rule's name.
