forked from I2P_Developers/i2p.i2p

* 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.
