    honor x-unique-cache-name header in flat mode, if present
    
    This allows things like different versions of the adobe-flash
    downloader that are given different names in a flat download
    directory (like in gentoo) to work in an http-replicator cache
    as well.  As long as the fetcher passes the custom name through
    the experimental header...
    
    NOT TESTED: I haven't tested this at all, but from code inspection,
    there appears to be at least two pre-existing bugs I didn't try
    to fix:
      1. If it is not in "--flat" mode, then there is nothing preventing
         a custom client from requesting
         "/../../../../../any/file/on/the/filesystem" (standard clients
         will simplify ".."s before sending the request) as long as
         the UID the process is running as can read it, including
         /etc/passwd or similar.  There may also be problems with
         writing to weird locations, although standard permissions
         renders this less likely.  This is a SECURITY bug, but
         fortunately (a) --flat mode is default on gentooo, (b)
         gentoo still defaults to http-replicator-3.0 on stable systems,
         which doesn't have this bug, and (c) 4.0 releases are still
         marked "alpha"...
      2. HTTP header names are not supposed to be case-sensitive, but
         this version does nothing to fold the case...
