RA-388: adding refapp distro as import scope; changing SCM to ssh

PR https://github.com/openmrs/openmrs-distro-referenceapplication/pull/24/files needs to be merged first. 
I suspect that since the distro is built on OpenMRS 1.10, this specific provided import (for emrapi-api-1.9) will be lost, but I also think that's okay.
