Feature Request: Adjust Threat border colour

[johnrogers]

Hello there, Switched over from Grid2 a few weeks ago and I am absolutely loving Cell.

The only option I wish I had that I could do with Grid was to adjust the threat border colour.

I use red as my health-deficit colour in Cell and having a fixed red threat border makes it quite hard to see if a tank or a player with threat has health missing.

Thank you.
