re-add MANAGER context bindings

these bindings activate before any other handler can process the
corresponding event and will block all propagation of the event upon
activation

as an example, the alt+wheel default binding for flipping desks currently
passes through a number of event handlers prior to activating the binding,
meaning that it's possible for the wheel action to have unwanted effects
when these handlers cause actions before the binding stops the propagation.
using a MANAGER context instead ensures that this is not possible
