Patch, originally from Bastian Kleineidam and savagely mutilated by me, to add the "display metadata" options: --name, --version, --author, and so forth.  Main changes:   * added 'display_options' class attribute to list all the "display only"     options (--help-commands plus the metadata options)   * added DistributionMetadata class as a place to put the actual     metadata information from the setup script (not to be confused with     the metadata display options); the logic dealing with metadata     (eg. return self.name or "UNKNOWN") is now  in this class   * changed 'parse_command_line()' to use the new OO interface provided     by fancy_getopt, mainly so we can get at the original order of     options on the command line, so we can print multiple lines of     distribution meta-data in the order specified by the user   * added 'handle_display_options()' to handle display-only options Also fixed some crufty old comments/docstrings.

    by fancy_getopt, mainly so we can get at the original order of
    options on the command line, so we can print multiple lines of
