Rotation timing improvements for Fire Mage APL

[NerdEgghead]

• Added API for querying the elapsed time since an Aura was last active.
• Implemented AuraInactiveWithReactionTime APL value, which can be used to increase the realism of certain sims by blocking the re-application of non-clippable DoTs on the exact timestep when they expire.
• Fixed APLActionWait to use the proper API for rescheduling the rotation action.
• Fixed DotRemainingTime and AuraRemainingTime APL values to correctly return 0 for inactive auras.
• Trigger reaction time waits after Living Bomb explosions for more consistent rotational behavior across small changes in the player's Haste value.
• Added reaction time check to Living Bomb usage in Fire Mage APL, which blocks unrealistic casts on the exact nanosecond when a prior Living Bomb exploded. Also added a wait condition to block hardcasts when Living Bomb is nearly about to explode. Both of these changes suppress the fake DPS discontinuity when dropping total Haste from 3262 to 3261 by ~3x relative to the prior APL.
• Removed MCD designation on Combustion so that it can be cast immediately after other spells in APLs.
