No obvious colour changes for Execute/Moment of Opportunity

[Mollerz]

Spellslingers, and I'm sure other classes, have an execute ability which increases damage when the target is under 30% hp. On Default/Biji nameplates, this colour is pink. We need to have the same thing so we know when to use our executes in our DPS rotations.

Also there is a mechanic called moment of opportunity in the game. When you stun or interrupt a spellcast on a PvE mob, you get a moment of opportunity, where they become stunned and their healthbar (On Default/Biji) turns purple, then there is also a ticking bar down the length of the nameplate to show how long MoO lasts for.
