Tunnels: Cleanup, catch more cases of zero-hop configuration
ClientAppConfig: Start i2ptunnel sooner
  Since BuildRequestor won't use a zero-hop exploratory as a paired tunnel
  for client builds, it's now safe to start client tunnels
  before the expl. tunnels are ready. This will save up to 90 seconds.

- SSU: Reduce ack delay
- Streaming: Reduce min RTO and flusher delay
- Tunnels: Reduce GW batching time

- Configure browser with routerconsole.browser (ticket #1159)
- Convert to ClientApp interface

- Rewrite to read and merge multiple files
- Include in update, use version in base dir too
- Increase limits
- Bug fixes

I2CP: Use configured leaseset keys if available

- cowpuncher is moving to rows.io

torsocks, so let's use torsocks directly

         Change default to RSA 4096
SigUtil: Add conversion methods for Java keys with unknown types

The webpack* and cloudflare* certificates are for ssl.webpack.de and
cowpuncher.drollette.com, respectively.  I'm removing the smartcom.org
certificate because it's unused.

The old certificate will not be replaced on the server yet.  The old cert is
SHA/1024-bit. New cert is SHA256/2048-bit key.
