Fire "dreaming started" and "dreaming stopped" broadcasts.
Dream manager now fires broadcast intents when entering + exiting
dreamland (except when testing).
Power manager can now listen for dreams ending, using polling only
as a backstop.
Also:
- Bullet-proof dream-manager/dream against known failure modes
- Add new read/write dream permissions
- Refactor dream-manager to delegate work + state management into
a new DreamController class, via a handler
