    Added qualifier to 'PackageConstraint' data type. · 79d562bf

    Refactored PackageConstraint in two ways:
     1) split it into a package name and a 'PackageProperty' to make
        the code a bit cleaner;
     2) changed PackageName to 'Qualified PackageName'.
    Added a Binary instance for Qualifier in PackagePath.hs (needed
    for PackageConstraint).
    Added pretty-printing code for PackageConstraint.
    For now, all the code that creates a PackageConstraint just sets
    the qualifier to 'unqualified', so this commit will not change
    the external behaviour of cabal-install.
