Another highlighting patch

[dlichtenberger]

Hi Tiark,

I didn't see Adriaan's highlighting patch in time so I ended up doing the same thing by myself. I'm using Google's prettify script (http://code.google.com/p/google-code-prettify/), and highlight both input (after sending the request) and output. Also, the highlighting is removed when editing a row, I think it's hard to combine the autoformatting with inplace editing. Anyway, tested with Chrome only, works for me so far, but I haven't used it extensively.
