patch applied (cabal): Do the cabal version check properly.

Tue Dec 2 07:54:10 PST 2008 Duncan Coutts <duncan@haskell.org> * Do the cabal version check properly. Instead of matching on the actual expression ">= x.y" we use the sematic view of the version range so we can do it precisely. Also use foldVersionRange to simplify a couple functions.
