Deskbar & PowerStatus: Realign Replicants

Added a new message constant to Deskbar kRealignReplicants which
is called to realign replicant icons. Add routing so that if you knock on
Deskbar's front door (Application) it will get routed to the right view, in
this case the repliant tray that knows how to realign replicants.

Send a message with this newly created constant in PowerStatus when
the width changes because you turned the label on or off. This makes
it so that when you show or hide the battery percentage it will not overrun
the clock.

Realign Replicants is a common case.

Fixes the rest of #8641
