Copperbox revision 3110.

I've made a new prototype for name rewriting.

Name rewriting is split into three phases - tokenizing, rewriting words and recombining. This strategy is not so general, but it does seem to capture the uses cases I have in mind for rewriting variable names to meet language conventions (i.e. C, IDL and Java to Haskell and vice versa). The prototype will need some polish - particularly I need to decide whether to support typed tokens (words) or just Strings. "Just Strings" will have a simpler API if I can get by without more types.
