Adding mechanism to compile Haskell.Data.* modules to Data.* modules

[viktorcsimma]

I've opened a separate PR for this. There is now a list of module prefixes which get compiled to corresponding Haskell modules. E.g. Haskell.Data.Map becomes Data.Map.

Actually, the test files used depend on maps; so I can only add them after they get merged (I'll include them in the Map PR)

Now added Haskell.Control, too (that is going to be important for #298).

Have you considered extending the "rewrite-rules" mechanism for providing these translation? IMO this is preferable to polluting the code base with such ad-hoc configurations.

I think it would be better for it to work out-of-the-box as the user expects them. But in fact, we could include some kind of "default" configuration file to which we move both this and defaultSpecialRules in Name.hs. Do you think about something like this, or do I miss the point?
