Accept wget result on any exit code.  #12.

Rationale:

    <yipdw> actually, on fourth thought, if ArchiveBot's wget processes,
            like, seriously fuck out
    <yipdw> why not upload that?
    <yipdw> it can be handled later on anyway

We might get junk in the upload queue, but that's okay:

    <ivan`> if you abort wget there's no wget log at the end of the
            .warc.gz
    <ivan`> I don't know if that matters
    <yipdw> yeah
    <yipdw> I'm not sure it does
    <yipdw> I suspect what we will do is write programs to handle
            ArchiveBot uploads
    <yipdw> mark the ones that look good, mark those that don't
    <yipdw> which I think is a saner approach anyway
    <yipdw> this way, we can be sure that if the bot starts downloading
	    it, there is always a way to get it out of its download
	    queue
Bump pipeline version.
