allow connections through proxies
core change: ports no longer in network byte order
Merge pull request #220 from louipc/master

new tox_bootstrap_from_address() behaviour and a minor ui change
redirect stderr before audio init to prevent error spam
name conflict with core function might cause linking error
don't allow DNS lookups when using a proxy + forced TCP & fix arg parsing
update DHTnodes
Add -b flag for debugging

For now this just prints messages to stderr, so the user should manually
redirect stderr to avoid breaking the ui. This can be later expanded
upon to provide debugging messages in the command window.
