* IE doesn't strip SPAN from <button> form fields, so add in a workaround
      within I2PTunnel.
    * Increase the maximum SSU retransmission timeout to accomodate slower or
      more congested links (though SSU's RTO calculation will usually use a
      much lower timeout)
    * Moved the streaming lib timed events off the main timer queues and onto
      a streaming lib specific set of timer queues.  Streaming lib timed
      events are more likely to have lock contention on the I2CP socket while
      other timed events in the router are (largely) independent.
    * Fixed a case sensitive lookup bug (thanks tino!)
    * Syndie cleanup - new edit form on the preview page, and fixed some blog
      links (thanks tino!)
