* i2psnark: Display base name, not torrent file name (ticket #985)
sort custom options
 * Streaming: Randomize end of first conn limit period
   to prevent correlation
 * Profiles: Ensure we select random peers even before the first reorganization -
   we were picking the not-failing peers in-order for early expl. tunnel builds
 * Tunnels:
   - Don't use fallback expl. tunnels as the paired tunnel
     for a client tunnel build.
     This will cause more client tunnel breakage but it's
     really bad to use a zero-hop for this.
   - Fix selection of an expl. tunnel close to a hash
   - Don't update build generation stat if the generation failed
   - log tweaks
