Add PACKAGE_TYPES choices to PackageString model

[mdhowle]

This fixes the AttributeError: 'PackageString' object has no attribute 'get_packagetype_display' exception.

By adding the choices kwarg for PackageString.packagetype, the get_packagetype_display() method is added to the PackageString model object.

Do you have the stacktrace where you come across this exception?
