* Added some basic guards to prevent multiple instances from running.
       Specifically, a file "router.ping" in the install directory which is
       written to once a minute - if that file exists and has been modified
       within the last minute, refuse to start up.  In turn, adjust the
       service wrapper to wait a minute before restarting a crashed JVM.
     * Create a "work" directory in the I2P install dir which Jetty will
       use for all of its temporary files.
     * Tell the browser not to cache most of the router console's pages.
