Add a facility to register and install actions at class init time. The intended use for these actions is for a) context and other model-based menus b) key bindings Most of these actions are going to be stateless, so add separate apis for the simple and stateful cases. We avoid creating an action group for these by teaching the action muxer about these actions. The action muxer also maintains the enabled state for these actions.
