Changed pom-files to refer to public ville-standardutils

Changed dependencies on ville-standardutils to be on the
publicly available release 0.0.2; also added entries
for handling mvn-repo on github for relevant vexer-packages
Added deploy-configurations

Changed vexer-model, vexer-helpers and vexer-stub to be deployed
as jars to mvn-repo branch. Added configuration to skip deployment
for vexer-stub-demo and vexer-template as their artifacts are
needed only for local testing.
