+ *    Unified blocklist/imagelist/permissionslist.
+ *    File format is still under discussion, but the internal changes
+ *    are (mostly) done.
+ *
+ *    Also modified interceptor behaviour:
+ *    - We now intercept all URLs beginning with one of the following
+ *      prefixes (and *only* these prefixes):
+ *        * http://i.j.b/
+ *        * http://ijbswa.sf.net/config/
+ *        * http://ijbswa.sourceforge.net/config/
+ *    - New interceptors "home page" - go to http://i.j.b/ to see it.
+ *    - Internal changes so that intercepted and fast redirect pages
+ *      are not replaced with an image.
+ *    - Interceptors now have the option to send a binary page direct
+ *      to the client. (i.e. ijb-send-banner uses this)
+ *    - Implemented show-url-info interceptor.  (Which is why I needed
+ *      the above interceptors changes - a typical URL is
+ *      "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ *      The previous mechanism would not have intercepted that, and
+ *      if it had been intercepted then it then it would have replaced
+ *      it with an image.)
