Builder|OS X: Automatically update installer package metadata

Prior to creating an installer package, the XML files are updated
with version information. (PackageMaker might pull some of this from
the binary metadata, though.)

Also, make sure Snowberry is repackaged for OS X whenever a build
is done.
