[plt-scheme] DrScheme colors

Since there seems to be some kind of wishlist ;] going I thought I could 
share my 2 cents about colors.

I've recently switched to a Zenburn[1] like (dark) color scheme for 
DrScheme and apart from the big contrast between the text and the GUI 
controls (which would be quite hard to fix) there are some things I 
would love to see improved:

1. You can't change the text background (which is a nice thing for 
paren-matching and errors/comments/todos).
2. The selection and error background colors can't be changed.
3. Keywords and parenthesis share the same highlight color.

Thanks for the great tool and keep up good work. :)

PS. Do you like the design of the editor framework in MrEd? It is quite 
difficult to understand (especially since there is no guide about their 
usage) and I have a feeling that the editing problem could be solved 
easier. I'm curious what's your view on this, since you've implemented 
quite a lot using the editor framework. With hindsight, are there things 
you would have done differently?
