fixes #1591 so folks can use 'profile-export' to export some or all profiles from the current version; or a specific version with an optional wildcard. e.g.:
profile-export /tmp/all-profiles.zip
profile-export /tmp/just-examples.zip example
fixes #1592 so that 'mvn fabric8:zip' propery includes the dependencies/groupid/artifact-requirements.json file; needed for java/war containers (and soon the OSGi resolver on OSGi projects)
