Properties (like enums) are not in the global namespace but only valid

Properties (like enums) are not in the global namespace but only valid
within a certain context. Give them an _Prop_ prefix, so they don't
accidentally obscure an element from another suite (as happened with
the Finder). Comparisons I'm not sure about, so I left them as global
names.

Also got rid of the lists if declarations, they serve no useful purpose.
