Changed code to use some dependent artifacts from outside the jar file,
that the client gets more configurable. Now the client-bean.xml,
clientKeystore.properties, clientstore.jks are externally adaptable or
exchangeable. DeviceLabResultClient.properties is enhanced to reference
to the now external client-bean.xml. Readme for the eclipse-build of the
executable jar also updated.
ClientCallbackhandler now takes keystore user / password from
clientKeystore.properties
