Shefki:
    - Fix Ticket #1005, Leader Icon does not hide after leaving a group.
    - LuaTexts: DruidForm(): Fix Moonkin and Flight Form detection.
    - Fix a typo
    - Flip some if then elseif blocks around so the most common conditions come first.
    - The model frame alpha bug applies to the dress up model frame as well.
    - Fix Ticket #600: Performance issue with pirate day easter egg.
    I just disabled the dress up model usage in combat.  It seems to avoid
    the problem with lag due to the use of that model since the lag is
    caused by the creation of new models.  If you're raiding or doing a
    dungeon your group is still going to show as pirates since their
    portrait will get drawn out of combat generally.
    - Fix flickering Portraits on some frames.
    The original fix that I'd made for the issue that happened after a scale
    or shape change was wrong.  The real problem was in our anchor code.  So
    I've reverted that change here.  That hack was ultimately causing the
    flashing since the effective scale code was triggering on some frames
    everytime.
    
    The real problem behind the scale/shape change was that the layout code
    assumed that GetHeight/Width returned the value passed to
    SetHeight/Width after a ClearAllPoints, which it does not if the
    previous anchors changed the size of the frame.  The fix for this is to
    set a temporary bogus anchor to allow access to these values.  I'm not
    100% thrilled with the solution to this, but I think the alternatives
    get even more ugly.  The layout code does run in combat, so I'll likely
    review this change again.
