Add color player on the panelEntity

[mimo]

When playing with combined victory conditions, the panelEntity can become quite crowded (typically n relics and n heroes for a herocide+relics game).

It would be nice (and quite helpful for observers) if the frame of each icon had the player color of the entity's owner (as is done for example on the garrison panel).

Would be good to have for alpha 23, but needs UnitAI review voluntarism.

How does it look ?

Move tickets to In-game UI as UI & Simulation got some sub components.
