Feature/bundle cli options with backwards compatibility

This is a compatible change.

The old `Bundler` task was repackaged and renamed as `Bundler Install` but retains the same @key so all existing plans continue to function.  

This feature branch:
* Renames `Bundler` to `Bundler Install`
* Adds `Bundler CLI`
* Refactored several of the Java classes for reuse
* Updated the readme with new information and more information in other areas

NOTE:
The integration test is commented out.  Otherwise, new tests have been added and all tests pass.

Fixes:
