remove network pause.
fix client repeat-disconnect loop.
removed resolver from getifaddr dance (not reqd) and updated getifaddr code (needs windowz/linux testing).
don't accept new connections if listenport bind fails (possible due to OS firewall settings).
only use upnp w/ipv4 addresses.
re: disconnect loop. Looks like ethhost session isn't deallocating once stopped. Thinking UI might have shared_ptr. For now, letting dealloc/quit continue as long as isOpen returns false -- maybe okay since network will be halted. Also, it maybe possible the issue is due to network thread not running after disconnect so packets aren't tx/rx to kill peer -- either way, it's possible remote end doesn't ack disconnect and timeout/force-close-dealloc is required, so will need more attention later.
remove unused method. skip upnp for ipv6.
reduce timeout, coding standards
Merge branch 'develop' into network
pr fixes. refactor of network code. moved network-start methods into static methods, as they can only be called during certain stages or do not need Host class. Mutex start/stop. Added m_ifAddresses and removed m_addresses. Rewrite determinePublic. IP address preference is now: user-supplied public > user-supplied private (if localnetwork enabled) > first public4 interface > upnp4 > first private4 interface (if localnetwork enabled) > unspecified. IPv6 addresses are currently ignored (unless manually entered by user) until link-local addresses can be properly detected.
