Make Ai able to leave from game by cryo unit./ AI AFK interface

[meaow589]

One thing to bear in mind is that of course the suggestion is that it be like cryo, so that in that case, the AI itself could just go into "suspended hibernation" and come back later if they didn't actually use the ghost command. I think that's good, but I also think that if we did it like that we might want a clear distinction between "Player of the original AI has just gone into AI cryo" and "Player has used the ghost command and not coming back"

Thank for everyone feedback it very good idea on your additional idea 
And for this comment.at first I want AI able to cryo and comeback but it seem like this might not a reason for me to make a AI slot open.And it might have problem if The original AI comeback after someone already take AI role. Lead to the question what happen if the original AI comeback when somebody already taken their place. So I cut the problem by not let it have so the different of using cryo between other role and AI is AI can’t use it for temporary cryo so they can’t comeback.
