   Configuration settings for each Resource Type

   - AllowedExtensions: the possible extensions that can be allowed.
      If it is empty then any file type can be uploaded.
   - DeniedExtensions: The extensions that won't be allowed.
      If it is empty then no restrictions are done here.

   For a file to be uploaded it has to fulfill both the AllowedExtensions
   and DeniedExtensions (that's it: not being denied) conditions.

   - FileTypesPath: the virtual folder relative to the document root where
      these resources will be located.
      Attention: It must start and end with a slash: '/'

   - FileTypesAbsolutePath: the physical path to the above folder. It must be
      an absolute path.
      If it's an empty string then it will be autocalculated.
      Useful if you are using a virtual directory, symbolic link or alias.
      Examples: 'C:\\MySite\\userfiles\\' or '/root/mysite/userfiles/'.
      Attention: The above 'FileTypesPath' must point to the same directory.
      Attention: It must end with a slash: '/'

    - QuickUploadPath: the virtual folder relative to the document root where
      these resources will be uploaded using the Upload tab in the resources
      dialogs.
      Attention: It must start and end with a slash: '/'

    - QuickUploadAbsolutePath: the physical path to the above folder. It must be
      an absolute path.
      If it's an empty string then it will be autocalculated.
      Useful if you are using a virtual directory, symbolic link or alias.
      Examples: 'C:\\MySite\\userfiles\\' or '/root/mysite/userfiles/'.
      Attention: The above 'QuickUploadPath' must point to the same directory.
      Attention: It must end with a slash: '/'

       NOTE: by default, QuickUploadPath and QuickUploadAbsolutePath point to
       "userfiles" directory to maintain backwards compatibility with older versions of FCKeditor.
       This is fine, but you in some cases you will be not able to browse uploaded files using file browser.
       Example: if you click on "image button", select "Upload" tab and send image
       to the server, image will appear in FCKeditor correctly, but because it is placed
       directly in /userfiles/ directory, you'll be not able to see it in built-in file browser.
       The more expected behaviour would be to send images directly to "image" subfolder.
       To achieve that, simply change
         $Config['QuickUploadPath']['Image']         = $Config['UserFilesPath'] ;
         $Config['QuickUploadAbsolutePath']['Image']   = $Config['UserFilesAbsolutePath'] ;
      into:
         $Config['QuickUploadPath']['Image']         = $Config['FileTypesPath']['Image'] ;
         $Config['QuickUploadAbsolutePath']['Image']    = $Config['FileTypesAbsolutePath']['Image'] ;
