Add support for nameplates marked as quest targets by Questie.

By default, Questie adds a "bag" or a "knife" icon near the nameplates of NPCs/mobs that are targets for one of your quests.

My suggestion is to add a separate color option for the nameplates marked as quest mobs by questie.
It will be also a great possibility to add an option to hide the Questie icon in case ThreapPlates already recognized it.

There is another little suggestion, to add an option to enable\disable faction icons separately, or for enemy/friendly to make it easier to recognize hosting players.

In total, over than this, I love your addon, it is really helpful and unique!

There is already a feature like this in the Quest widget - but that only works on retail, not on Classic as the quest tooltip information is not available in Classic. Questie adds this information, but Questie also shows a quest marker on the nameplate. That's why I rather disabled the Quest widget for Classic than extended it to also use Questie information. The only drawback is - as you noticed - that the coloring of nameplates is no longer available.
