[Koha] 1.2.3RC21

I think that 1.2.3RC21 is getting pretty close to release ready. If anybody can spare some time to install this release candidate and let me know of any bugs they find, it would sure help get it out the door faster. I'm also uploading a new kohacd image based on 1.2.3RC21. It should be available within the next 20 minutes or so... Steve Tonnesen
