BundleVersion and BundleShortVersion often not used

[jdelaune]

I needed to set a different bundleVersion and bundleShortVersion for a mas target. According to the config documentation you can set these properties for this target. However looking in the code for AppInfo these are never passed in. platformSpecificOptions comes from the mac target. Nothing is passed in from the mas target. However even bundleShortVersion isn't even used if set in the mac target.

These should be removed from the documentation if they aren't going to be used.
