Display more information about units, in game, before and after its creation.

I think it would be nice to include more information about units. For example, some buildings can store resources, but there's not indication what they can store until they are built.

@biels also mentioned that he would like to know more about about the attack and damage properties of units. When he was referring to whether a unit should be damaged by its own attack splash:

But then it should be shown on the command or somewhere when the splash harms itself or not
