Option for clan castle troops for attack and defense
I think that the clan castle should have an option for the troops inside to be used for attacking or for defense... Kind of like the king and queen have. The attacking function would not deploy them when you get raided and the defense option would be just like it is now: you can attack with them if you want and they will be deployed when you get raided. This is needed because sometimes during war or if you have troops for attacking that aren't really helpful for defense like some Giants or a healer, you can save them for battle instead of having them get killed and then having to wait for some new ones. On your war base, the castle is automatically set to defense mode.
