    * Write the native libraries to the current directory when they are loaded
      from a resource, and load them from that file on subsequent runs (in
      turn, we no longer *cough* delete the running libraries...)
    * Added support for a graceful restart.
    * Added new pseudo-shutdown hook specific to the router, allowing
      applications to request tasks to be run when the router shuts down.  We
      use this for integration with the service manager, since otherwise a
      graceful shutdown would cause a timeout, followed by a forced hard
      shutdown.
    * Handle a bug in the SimpleTimer with requeued tasks.
    * Made the capacity calculator a bit more dynamic by not outright ignoring
      the otherwise valid capacity data for a period with a single rejected
      tunnel (except for the 10 minute period).  In addition, peers with an
      equal capacity are ordered by speed rather than by their hashes.
    * Cleaned up the SimpleTimer, addressing some threading and synchronization
      issues.
    * When an I2PTunnel client or httpclient is explicitly closed, destroy the
      associated session (unless there are other clients using it), and deal
      with a closed session when starting a new I2PTunnel instance.
    * Refactoring and logging.
