* Throttle: Reject tunnels for first 20m uptime (was 10m)

* TunnelPeerSelectors:
       - Re-enable strict ordering of peers,
         based on XOR distance from a random hash
       - Restrict peers with uptime < 90m from tunnels (was 2h),
         which is really 60m due to rounding in netDb publishing.
    * i2psnark:
       - Limit max pipelined requests from a single peer to 128KB
         (was unlimited; i2p-bt default is 5 * 64KB)
       - Increase max uploaders per torrent to 6 (was 4)
       - Reduce max connections per torrent to 16 (was 24) to increase
         unchoke time and reduce memory consumption
       - Strictly enforce max connections per torrent
       - Choke more gradually when over BW limit
