[BUG] Screech threat component not tracked

[alan-smith-vt]

What steps will reproduce the problem?

1. Have pet attack one mob, shoot a second mob and bring it over to pet. After a couple screeches, the second mob will switch aggro to pet. Threat meter will show pet at 0 threat for that mob.
2. Even if there is only one mob, the threat tracked will be wildly off after a minute or two of combat as screech every 4 seconds generates hundreds of threat over time. This causes the entire addon to be unreliable when using screech for fights lasting more than a few seconds.

What version of ClassicThreatMeter are you using? (Stating 'latest' is not useful)

1.06

Do you have an error log of what happened?

Not applicable, I don't think. I could generate a combatlog if it would help.

Any additional information? (example: WoW language if not English) (Attach screenshots here if available, do not link externally)

Note: Screech is a hunter pet ability available to bats, carrion birds, and owls. Screech does some minor damage to the main target, as well as a short range aoe attack power debuff which causes threat to all targets affected. The implementation of tracking this would be the same as demo shout I think.
