Allow {civ} replacement for auras.

Example of use (following an idea of leper): adding {civ}_teambonus in Player template and getting rid of all the civ specific one in the Player civ specific template.

That should be done in Aura.js Don't forget to check the gui code (tooltips, structure tree,...)

This is basically about doing the same replacement as is currently done for training entities in ProductionQueue.js. (Also consider factoring out that replacement if it is easy enough. Also #4589 would be related.)

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

Player entity does not have ownership (Thinking about it, it would be odd if had). So there would need to be civ code inside identity component in each of {civ}_teambonus files but that is just exchange one line of code with another ( I do not think it is worth it ), so I am abandoning this ticket.
