[applets/taskmanager] Offer better options when activating grouped tasks
Currently we get many complaints about the behavior of clicking on grouped tasks, especially for the Icons-Only Task Manager, where the Present Windows effect is always used when available.
This commit overhauls what happens when you click on a grouped task to offer three options:
- Show tooltips (new default setting)
- Show Present Windows effect
- Show textual list (AKA group dialog)
The user is now free to choose in the settings window which visualization best suits them, and the default behavior is now unified between the Icons-Only Task manager and the traditional Task Manager
This commit does not implement the most heavily-requested option--to bring forward all of the windows belonging to a grouped task (https://bugs.kde.org/show_bug.cgi?id=370258)--as it is still blocked by some technical isues related to stacking order and outstanding UX uncertainty regarding what should happen when one or more of the windows in a group happens to beminimized. However, since this commit introduces a config UI for choosing the desired behavior when activating a grouped task, there is now a place to put that option once it is implemented.

Here's how the settings window's Behavior page looks now:
