Beta4

Note: pull request that goes along with this release was mislabeled as Beta3.

Release summary

• Added API support for those who want to use DeepViolet features
  in their own projects. See com.mps.deepviolet.api
• Added samples package with sample code to demonstrate new API
• Refactored existing code for the command line support and UI to
  use the new API.
• 2 new command line options for debugging added, -d and -d2.
  d turns on Java SSL/TLS debugging. -d2 assigns DV debug
  logging priority.
• Generated JavaDocs for Public APIs, see com.mps.deepviolet.docs
• javadoc.xml added to generate JavaDocs
• Support for dock icon on OSX for the UI

The new feature means 3 jar binaries will be created for every release,
dvUI.jar, dvCMD.jar, dvAPI.jar

Essentially, all jars contain the same code with a slight change to
the manifest to each that enables running via desktop double-click.
