    README: Slightly expand and reorganize.
    
    * Mention 'mdoc' and note its origin in BSD.
    * Recast to prevent inference that (g)xditview came from BSD as well.
    * Organize "contrib" components into their own paragraph, for a better
      parallel with the "LICENSES" file.
    * Mention 'chem' since it is a well-known AT&T preprocessor.
    * Add material about development, referencing "HACKING" and "MANIFEST".
