timeswitch node: time zone support; do not mark as misconfigured when sunrise/sunset not used and lat/lon not given (#757)

Browse Source 
* timeswitch node: a) do not mark node as misconfigured if sunrise and
sunset are not used and latitude/longitude are not given. b) support for
specifying time zone when on and/or off times are not specified as
sunrise and/or sunset.

* Replaced moment dependency with spacetime

* Timezone defaults to UTC for compatibility with previous node version
