What release tarballs? I zip

Actually they're not in there due to size reasons, but they're always available in the SVN. If it becomes a serious issue (i.e. unable to obtain source of a certain revision from the SVN) then maybe. Size is also the reason why I didn't include ioq3ded and the rest of the binaries and had that on the SVN instead as well.
I'll think about it for the next version. I'm striving to keep a "happy, compact balance" on size for windows and linux
