Rubinius has added support for RUBY_ENGINE_VERSION to help ruby switchers distinguish between the ruby version (1.9.3) and the implementation version (1.7.9). I think JRuby would also benefit from exposing this constant.

It would be really nice to have a cross-implementation, standard way of checking the JRUBY_VERSION equivalent. 👍

Support RUBY_ENGINE_VERSION

`RUBY_ENGINE_VERSION` was [added by Rubinius](rubinius/rubinius@8212c46) for reporting the version of the Ruby engine. It has also [been proposed for JRuby](jruby/jruby#2746), where it would be equivalent to `JRUBY_VERSION`. In CRuby `RUBY_ENGINE_VERSION` would be the same as `RUBY_VERSION`.

Seems like a good idea to me...RUBY_ENGINE + RUBY_ENGINE_VERSION is like JVM's java.vm.name and java.vm.version.
