Syntax highlighting is too eagerly converting to HTML entities

(Ported from jquery/2012-dev-summit#90)

Seems that syntaxhighligher's JS brush has some "preprocess" regex that is actually just destroying many of our code blocks by converting things to entities, see:

@bobholt traced it back to https://github.com/thlorenz/node-syntaxhighlighter/blob/master/lib/scripts/shBrushJScript.js#L23. If that's commented out, the entity conversion isn't happening.

Fixed!

This seems to be limited to the first single quote of each line.

The problem is that the markdown parser is encoding script blocks. I'll work on getting it to not do that.

Seems like this is fixed by #23
