Infus:
    - Add in Combat Condition Trigger
    Trivial to add, and more flexibel than a load condition. The Conditions
    already react to PLAYER_REGEN_(ENABLED|DISABLED)
    
    Ticket-Nr: 656
    - Fix group auras after closing Options
    Closing the options would not correctly update the group auras
    if not in a group at all and only group auras where used.
    
    Noticed while fixing related bug.
    - Remove recent_chages code from BuffTrigger.lua
    This caused some auras to not show up on loading.
    
    In the bug reports case, the code was tracking buffs only
    outside of combat.
    
    The sequence of events:
    - Apply the buff
    - Enter combat, unloading the aura
    - Leave combat, loading the aura
    
    Loading a aura causes a ScanAll(), in the bug reports case
    this would call AssertAura, but due to the data being identical
    to the data gathered before combat, the aura_cache would indicate
    no change. Yet, after a load we want to update everything.
    
    I think this has been always broken, as I don't recall changing this
    logic.
    
    The fix is, ignoring whether the aura_cache already knew that buff.
    Since the return value of AssertAura/DeassertAura is the only place
    where recent_changes is used, purge it from everywhere.
