Compile to ES5?

[GerHobbelt]

Latest jison 0.6.0-191 uses a few ES2016 features (string templates, ...args) which are not supported in older NodeJS and/or browsers (Node 5.0 and older: TravisCI fails ATM: https://travis-ci.org/GerHobbelt/jison )

It might be advisable to pull jison et al through babel before publishing in order to prevent issues stemming from running jison in older environments.

Note:
extra checks required to ensure the generated parsers and lexers are ES5 safe!

[GerHobbelt]

Relevant common code which was done in ES6 (at least some bits of it) has been moved to a separate subrepo: https://github.com/GerHobbelt/jison-helpers-lib and is babel-compiled in the build process there.

That at least covers it for the TravisCI tests in Node 4 and Node 5 environments.

Which leaves rollup+babel support for the entire thing...

[GerHobbelt]

Done. jison and its libraries/packages are now processed through rollup+babel and the monolithic results are presented in the various dist/ distribution directories.

The only thing that still bothers me is compiling ES6-action-code-carrying grammars in non-ES6 environments (NodeJS, among others) but that is a different issue.
