Add "Stop" to stop current action list/trigger

Currently, when a list of actions is being executed (e.g. a button press triggering 100+ other actions with many long delays), BTT just continues with the actions until it is done, and there is no way to stop it unless one force quits BTT.

Please add a way to stop these actions, or even better, a touch bar button with an "On/Off" switch, that stays on when one initially touches it, and turns off when touching it again.
