... instead of having the indirection of the global object pool.
ModeManagerPrivate has been maintaining the list of instantiated
modes by tracking (all...) pool object additions / removals. This
can be achieved more directly by calling functions from the
IMode base constructor/destructor.
The pattern used deviates a bit from the otherwise used 'static
QList<Foo *> allFoos();' acessor pattern as there is some sorting
logic etc. associated each time a mode is appended.
Sticking to the preexisting structure seemed less effort for now.

If modes provide a QMenu, a little arrow is shown next to the mode icon.
If the user clicks there, the menu is shown instead of changing the
mode.
Limitations: Modes need to provide some QMenu instance already when they
are added to the object pool. Setting or removing the menu later will
not update the UI.
