/**
* A dispatcher that serves as a proxy for style commands with arguments
* i.e. .uno:StyleApply?... in order to provide useful status updates to
* generic UI elements such as toolbars or menubar. It listens to special
* status commands, and computes a boolean status out of them. Then it
* forwards that boolean status to the listener, as if it was the status
* of the original command.
*
* Note that the implementation is minimal: Although the UI element appears
* to be the owner of the dispatcher, it's still responsible, as usual, to
* call removeStatusListener same amount of times as addStatusListener,
* otherwise the dispatcher might not be destructed. In addition this
* implementation might hold a hard reference on the owner, and it's the
* responsibility of the owner to destroy the dispatcher first, in order
* to break the cycle.
