Comment 2 for bug 894913

I'd like to request these instead:

StealthOnDeploy=bool
FlatWhenDeployed=bool
InvunrableWhenDeployed=bool

Now, StealthOnDeploy removes the need for SelectableCombatantWhenDeployed and allows the unit to actually dissapear from enemy screens rather than just being unselectable. FlatWhenDeployed is necessary, and I'll let you keep InvunrableWhenDelployed= to couble with the tag that makes units undeploy after a certain time.
