applets/taskmanager: improve non-default grouped Meta+[number] UX
requested to merge ngraham/plasma-desktop:better-meta-num-activation-behavior-when-using-non-default-grouped-task-activation-behavior into master
Clicking a grouped task respects your user preference with regards to behavior (it's configurable). However, when activating a grouped task using Meta+[number key], the only behavior that really makes sense is cycling between windows; all other behaviors are quite mouse-driven, and since you already had your fingers on the keyboard, using a mouse-driven UI here doesn't make much sense.
Accordingly, always use the cycling behavior when activating a grouped task with Meta+[number key].
