No jruby support

[dmcnulla]

I use this religiously because I love to document my cukes. I really appreciate that you made this.

Recently I started supporting jruby for varioius reasons. Yard-cucumber doesn't work on jruby because jruby doesn't compile redcarpet. I tried with kramdown, but I had an error
ameError: wrong constant name ::Kramdown::Converter::SyntaxHighlighter::Coderay
