font lock on various keywords

[pedz]

I was hoping that "describe" and other rspec words would be colored for me.

Does anyone else want that?

I might try and cobble that together -- hoping to steal from cucumber's "feature-mode".

rinari added a similar feature recently, I think it's implemented a bit simpler than in feature-mode.

I think the code looks good enough without additional highlighting, but if you do end up writing this, please don't use font-lock-function-name-face and font-lock-keyword-face.
