    Oops, use the right description string for the last commit.
    Ticket 518: Tooltip for HappinessIcon module.
    Make the default group actually be the Party group in the config dialog.
    If the Party group doesn't exist it'll just be a randomly selected
    group.
    Ticket 465: Misplacement of text following a blank text.
    Replace Class: Short with code that only shows the class and rename the
    old Class: Short to Class: Short level and race.
    Ticket 512: Dropdowns too narrow to fix text.
    Ticket 515: Fix disappearing rune indicator.
    Debug code to help try and trace ticket 475.
    Ticket 457: CastBar disappears after opening the WorldMap and closing
    it.
    Missed some spots  for the previous change for the CastBar.
    CastBar: Turn the timer on and off as needed rather than running all the
    time and checking if needs to do work.  Should improve performance
    slightly when nobody is casting.
    Remove text justification from the overlapping text code.
    Final work on text justification.  Multiple texts in the same anchor
    point should now be justified properly.
    Ticket 514: EnableMouse is protected and needs to be done out of combat.
    Hide the options when the HideBlizzard module is disabled.
    Fix a logic error that made HideBlizzard hide all the blizzard frames
    when disabled.  When it really should leave them hidden.
    Fix duplicate calls to MaxPower in two prebuilt LuaTexts codes.
    First pass at setting text justifications.  Only justifies the
    first text in a given anchor location.
Cameron Knight:
    change _G.expect to instead be PitBull4.expect so that it doesn't pollute the global namespace.
Shefki:
    Ticket 505: Outside Left anchors not moving the proper direction for the
    margin.
    Ticket 503: VisualHeal module not properly dealing with multi-target
    heals.
    Ticket 490: Config mode doesn't respect CastBar's show icon
    configuration.
    Use the proper config value to pad in both directions for outside corner
    anchors.
    Ticket 261: Inside bottom anchors were using padding in the opposite direction it
    should have been.
    Small code cleanup on some of the event code.
    Fix problems with pet frames not fully updating becuase not all the
    information is available when UNIT_PET fires.
    Tab the Groups configuration for usability reasons.  People keep
    accidentally using the Unit group dropdown to try and change the current
    group.  This of course causes great confusion.
