(svn r4060) -Codechange: [OSX] made the release target (in os/macosx/Makefile) easier to use since it gives the release disk image the right name automatically
it now uses REV instead of RELEASE, which means RELEASE is not needed to be set manaully anymore
it also automatically adds "-jaguar" when making a build aimed at OSX 10.2 (codenamed jaguar)
