up the commons.io version to 2.4
Ensuring updated maven root pom is in enterprise repo.
Moved BaseFileSystemSpout and HdfsFileSystemSpout to lumify-public so they can be used by the lumify-twitter project.  Moved HDFS-based twitter ingest bolt to lumify-twitter.  Reconfigured lumify-twitter’s StormRunner so it accepts the parameters —no-query and —no-file to turn off either the streaming or HDFS-based spout.

Updated ContentTypeSorterBolt to ensure queue target directories exist before it tries to move files to those queues.  This is critical for the .lumify-queue method of identifying processing queues though we may want to look into some kind of check to avoid invalid queue names, maybe restricting them to [a-zA-Z0-9_]*?
start maven build-number plugin configuration
Modified POM files to generate build timestamp and git commit hash properties.  Added lumify-build.properties files to the lumify-web, lumify-storm, lumify-enterprise-storm, lumify-twitter and lumify-facebook projects.  Added LumifyVersionService interface and PropertyLumifyVersionService implementation that read these properties files and expose the version String, git hash and build timestamp to the application.
