Now that this beast was officially declared as the Apache 2.0 stuff, let it
also say this in his Server headers while testing.  Those who dislike numbers:
feel free to name it "foo" or whatever meaningless if it's important that we
still do not use numbers. I just want that the version corresponds to the
repository area, because I often get confused by running different Apache
versions on my development box.
