RAVE-59: Create automation for building of demo package
See: http://issues.apache.org/jira/browse/RAVE-59
- Intermediate commit:
  - adding a "dist" profile to automate the building (run with mvn -P dist from rave-project)
    - enforce maven-clean-plugin to execute to ensure cleanly build artifacts and demo packages 
    - ensure default goal maven install to get rave-shindig and rave-portal properly build and (locally) installed first
    - execute cargo:configure and cargo:package during/after rave-portal install 
- Still to do:
  - add an maven assembly configuration to add additional needed configuration files (overrides) and docs in the demo package
  - execute maven assembly plugin to build the final package
