Extract CLI Java components into new submodule

* Create new sub-module asciidoctorj-cli: migrated 'org.asciidoctor.jruby.cli'
classes and related tests to it.
* Created CliOptions in AsciidoctorUtils from values in AsciidoctorCliOptions
to avoid circular dependency.
* Updated README with new sub-module information.
* Fix jar names in command in README.
* Minor refactors and fixes.

Fixes asciidoctor#246
