Pause button for training in barracks

i think it will be a good idea to have a pause button to pause training in a barrack. this will allow certain troops to be processed before the ones in other barracks and the user will have control of which troops are processed first

otherwise currently the user has to go for removing all the troops from training every time he wants to train troops in one barrack before others or plan placing troops equally across barracks

Not sure if any of you have felt the need

We may also have remove all (troops in training) button
