Use CodeRay for syntax highlighting

#142

We could stop using SyntaxHighlighter in the admin section if we render the diffs using the CodeRay gem.

the use of CodeRay is also demonstrated in the Create a simple code snippet app with Rails article in the third issue of Rails Magazine.

    I just found out that there's a gem that can integrate the CodeRay functionality in RedCloth, imaginatively named Redcloth with CodeRay.

    This could be a way of reducing the amount of JS that we employ even further.

    I have just discovered that CodeRay itself has a ForRedCloth "hack":

    A little hack to enable CodeRay highlighting in RedCloth.

    Based on a quick test I did in irb, it seems to work!

    I'm already working on this.

    RedCloth 4.2 doesn't work with the stable version of CodeRay. I had to get the SVN version, build the gem and install it. Worked fine.

    One more problem tho: how do you get code on more than one line?

    And regarding your description "We could stop using SyntaxHighlighter in the admin section", I think we can get completely rid of it. Everywhere.

    Do we have to use the Redcloth with CodeRay gem?

    That allows multi-line code samples with a special <source> tag.
