Dynamic peers

[cyisfor]

I basically wanted to rewrite dynamicEndpoints.py using tools/* instead, since those are maintained.

But since logging is borked, and probably not intended to be used as an event signaling interface, I ended up using a polling algorithm instead, which should actually be easier, since it doesn't require the node to log anything, or remember subscriptions.

Just tested it, and got my netbook to connect to my home server. Still can't loop out of the LAN and back into it by trying to connect with my external IP, but that's b/c my ISP's router sucks, nothing about cjdns.

Also check out promise.js. It's like the regular nodejs promise, except that I'm not lying when I say mine is "bare bones".

This is not directly related, but FYI:
zHIVErbox is an Armbian (Debian) based distribution, that ships with Cjdns out-of-the box and uses dynamicEndpoints.py + KadNode to connect dynamic peers via a decentralized DynDNS (Kademlia DHT).
