Merge pull request #214 from elliottwilliams/patch-1

Add lua language support
add patched highlight.js as submodule: vanilla highlight breaks badly when docco-ing jison files, for example.
assume default 'highlight' language is 'text': just making sure we always pass a non-empty language string to highlight.js. Then our highlight.js clone can take care of the b0rkb0rkb0rk in there as per https://github.com/GerHobbelt/highlight.js/commit/9d38cfd2a75dae77f475c7b83648cd3c0f0888c3
gitattributes: making sure files are always UNIX format, irrespective of the platform/rig you're developing on
regenerated
tweaked the 'parallel' stylesheet to show <code> blocks and blockquotes in a better light: blockquotes are used for remarks-like paragraphs of text, not straight code.

<code> inside headers now shows up much better too.
