config-check

Copperbox revision 3074.

Some changes to type names and some code clean up.

Initially this revision was an attempt to simplify the implementation of the CheckCode monad by changing success from Okay True (with both Okay False and Fail msg as failure) to Okay () as success and Fail msg as failure. However this change made it difficult to write Applicative checkers (they needed an extra lifter) and imall became more difficult to think about.
