Turn off non-compiled code highlighting of slime

On dark background it's really annoying. This should be an optional feature IMO. As slime developers don't think the same we should turn it off in slime-ros instead.

Hm, I kind of like the feature. Plus, the default background is white anyway and it doesn't look so bad there. Could you instead maybe change your local color of the non-compiled code?

Well if you start emacs in terminal it's gray highlighting on dark-gray background. People start emacs per ssh and get all confused by what's happening, especially the students, and it's hard to find out where the highlighting comes from.
But, good point, thanks for your input. I'll try to make it depending on the background instead. Maybe then the slime people will accept a pull request.

Nah, its okay for me to change the default. I can just change it for me locally if it annoys you. But making it depend on the background is a good idea as well.
