windowManager: Refactor workspace switching animations
Besides the separation into distinct functions, the stored data has been made able to generically store windows from all surrounding workspaces. All while keeping a special mode to animate between two workspaces (The usual till now), this is the only mode exercised so far. In order to ease animations, all window groups are now children of a common container, which is then animated.
