Changes:
- Implement tracking of remote ports: shows which ports the host is making outgoing connections to. Long time feature request.
- Bugfix: when the capture interface goes down, exit instead of busy-looping forever.
- Fix "clock error" due to machine reboot.
- SIGUSR1 now resets the time and bytes reported on the graphs page.
- Account for all IP protocols.
- Change the default ports_max to only twice the default ports_keep.
