Cancelling Move, Melee or other actions#1136

Playing on Mac OS when you have clicked one of the action buttons e.g. Move, the button changes to the selected state and you can interact with the Move UI around the current unit.

Currently I can only back out of the Move by pressing the escape key, pressing any of the shortcut buttons for actions Z X C V does not change to the other actions, neither does clicking on the other action buttons.

I would have expected clicking on the action button a second time to cancel the selected action, and probably clicking on the other actions to change to that action.

• Clicking currently active action button should cancel that action
• Clicking on another action would cancel the currently selected action and select the second clicked action.
• Pressing the shortcut key for the current selected action should cancel the current action.
• Pressing the shortcut key for an action other than the current selected action would cancel the currently selected action and select the action of the pressed shortcut.
