Benjamin Staneck:
    - let the cache overwrite name<>icon mappings when there is a newer (higher id) icon for an old spell.
Infus:
    - Fix talent multi selection
    The code trying to upgrade use_talent ensured that it was always true or
    nil. That's actually not required and prevented the false state, which
    is multi selection.
Stew:
    - yOffset still bugged for invisible auras
Infus:
    - Check if pet is alive for "Pet Active" trigger
    After a pet dies UnitExists("pet") still returns true until the
    pet vanishes. That's unlikely to be what anyone actually wants
    out of that trigger.
    - Fix ignore rune cd interaction with inverse
    - Aurabar: Fix modify to correctly apply text/timer font changes
Hendrik Leppkes:
    - Fix type check
    - Stop leaking "trigger" variable
Benjamin Staneck:
    - whitespace commit to get the packager going
    - Changes SetTexCoord calls to work with Masque skins that do SetTexCoord calls themselves.
    With this patch, WeakAuras' SetTexCoord calls use the Masque's skinned values as base values, which are then modified for the Zoom levels set in the WeakAuras options.
brawne:
    - make sure ItemEquip auras untrigger when item is unequipped
Infus:
    - Add misssing Blizzard Textures
    Also rename the group from Catacylsm Alerts to Blizzard Alerts,
    which is more accurate.
Timmeh:
    - Replace commented ButtonFacade support with working Masque support.
Hendrik Leppkes:
    - Add replacement functions for ActionButton_(Show|Hide)OverlayGlow to avoid taint caused by using them.
    - Add a mechanism to override functions for scripts
Infus:
    - Fix renaming auras
    - Aurabar: Fix vertical progress bars to not shrink, but crop textures
    Ticket-Number: 169
    - Pet battles: Actually listen to the events
    Ticket-Number: 107
    - DK: Fix ignore rune cd
