`StandardMatrixInterfaceCommandDispatcher` should accept something like Draupnir's `ManagementRoomDetail` to provide redundancy in access control.

// We want to move the ManagementRoomDetail into this library and have it
// provided here as CommandRoomDetail.
// It should also scrap management prefix to the room/roomID properties.
// It's up to you whether you want to have the `isPublic` method here.
// It won't be relevant since the `isModerator` method is abstract.
// `isModerator` should probably be changed to `isCommander` or something.
// I don't really like that we're reinforcing ACL over caps here,
// but I guess that's just how this shit works.
