[R-SIG-Mac] R.app bundle keys

[Paul Roebuck]

Suggest adding the following required application key
in 'Info.plist' immediately prior to CFBundleVersion.

        <key>CFBundleShortVersionString</key>
        <string>1.13</string>

Format for the following two keys in the 'InfoPlist.strings'
does not currently match the suggested format. For 10.4,
Apple recommends not adding the version information to
CFBundleGetInfoString but since the same build services
both Panther and Tiger, this change is not yet feasible.

CFBundleGetInfoString = "1.13, <Copyright symbol> R Foundation for
Statistical Computing, 2004-2005";
NSHumanReadableCopyright = "<Copyright symbol> R Foundation for
Statistical Computing, 2004-2005, All Rights Reserved.";
