Title: Events when changing previewing mode or changes state

Re: https://github.com/jejacks0n/mercury/issues/190#issuecomment-4663955

* Generates `toggle:preview` mode event when entering/leaving preview mode.
* Uses `set-changes` event rather than directly setting Mercury.changes
* Triggers `changes` event whenever changes state toggles

For preview only, no specs yet. Bundle is hanging and I cannot run existing specs. Hoping master is clean.
