quickcheck-rematch won't compile with ghc >= 7.6.1

[jh3141]

The .cabal file for quickcheck-rematch specifies the required version number of base as == 4.5.*, which means it can only be build with ghc versions 7.4.*. I would suggest that, as with the other packages, the base version should be specified as >= 4.5.0.0 && < 5.
