Add Friend and Foe Colors

[William Weber Berrutti]

In AoE2, there's a hotkey that, after pressed, colors the player as blue, allies as yellow, and enemies as red. That makes it easier for the player to identify who's ally and who's enemy, specially in matches where it's difficult to identify it (like, for instance, 4vs4, or enemies and allies with similar colors). Maybe this could be interesting to be added in OpenHV?
