Changed syntax of Set{Input|Output}Filter. The list of filters

 Changed syntax of Set{Input|Output}Filter.  The list of filters
     must be semicolon delimited (if more than one filter is given.)
     The Set{Input|Output}Filter directive now overrides a parent
     container's directive (e.g. SetInputFilter in <Directory /web/foo>
     will override any SetInputFilter directive in <Directory /web>.)
     This new syntax is more consistent with Add{Input|Output}Filter
     directives defined in mod_mime.  Also cures a bug in prior releases
     where the Set{Input|Output}Filter directive would corrupt the
     global configuration if the multiple directives were nested.
