Subject [GitHub] tika pull request: Make Tika recognize empty and spanning ZIP file...

    Make Tika recognize empty and spanning ZIP files too

    As it turns out, magic differs for non-empty, empty and
    spanning ZIP files. Tika recognizes only the non-empty ZIP files.
    
    Magic for empty ZIP file is validated with hexdump:

    Also described on Wikipedia
    http://en.wikipedia.org/wiki/Zip_(file_format)
    (see sidebar with Magic Numbers)
    
    Am completely unsure about MIME types `application/vnd.zip.empty` and `application/vnd.zip.spanning`,
so please correct those to appropriate values.

    Added two more magic entries for ZIP files.
    
    As it turns out, magic differs for non-empty, empty and
    spanning ZIP files.
