Shefki:
    - Fix problems with AceAddOn upgrades.
    Bad ckknight, you can't just overwite mixins.  If you do when the
    library gets upgraded then your function gets ovewritten.  Espcially
    when your function doesn't even have the same parameters.
    
    Renamed PitBull4:EnableModule to PitBull4:EnableModuleAndSaveState
    as well as PitBull4:DisableModule to PitBull4:DisableModuleAndSaveState.
    - Fix Clique support for AnyDown for Singletons too.
    Last commit only fixed it for Groups.
    - Fix support for Clique's AnyDown support.
    Was broken by the work on click-through frames.  Have to play some games
    to avoid infinite loops by Blizzard bugs.
    - HideBlizzard: Tweak raid hide/show feature.  Defaults to off now.
    Rational for changing the default is as follows.
    
    A lot of people do not use PitBull4 for raid frames.  If they're using
    some other addon it should hide this, not us.  Same reason we currently
    don't have a Raid group already setup.
    
    Additionally, many people were confused by not being able to find the
    Raid Manger.  Since the Raid Manager lets you do set flares and do role
    checks which are not provided anywhere else or in PitBull4, we also
    should not be hiding by default.
    
    People who want to hide only the raid frames and not the manager should
    use the Hide button on the Raid Manager.  If you want both gone then you
    can use the setting under Modules, Hide Blizzard.
    
    This commit also fixes our hiding of the Raid Manager/Frames to
    no longer break the Raid Manager.  It will properly show all the
    features if you are a raid officer if you show it after having it
    hidden.
    
    Finally, this commit makes it so when we do not cause the Raid Manager
    Hide/Show buttons to be out of sync with the actual state of the Raid
    Frames.
    - Apply another workaround for ticket #475.
    - Fix Ticket #803: Animated bars flash when set to Low or Background stratas.
    Turns out Blizzard changed a behavior of AnimationGroups in 4.0.1, they
    now call OnUpdate immediately after Play() is called and GetProgress()
    returns 0 for this call, which caused the errors as the formulas were
    not designed to work for this.
    - Increase search space for temporary weapon enchant spell icon guessing.
