Port the cybozu command line utils

See https://code.google.com/p/language-detection/wiki/Tools

The ported classes should be moved to proper package name space. Remove deprecated classes. Perhaps include the GenProfile from free-text feature from lang-guess too into the command line tool.

Discuss whether to add another standalone jar with all deps to support java -jar invoking of cmdline tool.

We could make it a Maven multi-module project. The core is what there is now. And those would go into tools. This way the users of the core don't get more dependencies they don't need. They just put the core as dependency. And the tools module can build its own jar. The tools then depends on the core.

What do you say?
