[svengali API]: new transition syntax with `goto('destination')` and reentry to a state with `reenter()`

Reentry into a state is a way doing parameterized states.  Instead of
forcing a transition to the same state, which has the downside of
reentering all parent states.  I believe `reenter()` is more intuitive
and localized.
