version-script: add SDK Product Build Version
Makefile: typo
For the "Vole->About Vole" box, change the build identifier from
AA-YYYYMMDD to YYYYMMDD.HHMMSS.KK where KK is the major version of OS X SDK
( 4= tiger, 5=leopard and so on). The old build identifier simply did
not work on anything other than Tiger builds.
