Now looks at multiple XML tags to determine product version in MacOS's Info.plist. Furthermore, if MacOS fails to find the package, it can prompt the user to locate the product, so there're some new entry points in the UI abstraction. Also added a cheezy means to check multiple versions, such as: "1.0 or 1.1 or 1.2" Obviously, that needs more robustness.
