Updating tickets (#950, #1538, #1644, #1661, #1662, #1716)

Just for the kicks

(In revision:10974acfe85fe3b1766cf255d3535b9ff8644404) make it possible to programmatically deploy (e.g. remotely), see #1644

- add Deploy to Props, which is used as the basis (overridden by
configuration)
- utilize general mechanism .withFallback (introduced on Deploy,
RouterConfig and Scope)
- actually pass Props over the wire when deploying remotely in order to
retain settings (this was an oversight before)
- write tests for the new functionality
