Pulse the screen edge glow smoothly and drive it from events

Browse Source 
The glow stepped its color ten times a second and re-checked combat,
health and death on every step. An animation group now shifts the color
along an IN_OUT curve and pauses while the glow is hidden. Combat,
health and death update from their events. Aggro has no event, so a
ticker polls it every .3s, matching UnitHasAggro's cache, and only while
that glow is enabled.
