Ipns name resolution

This branch is not yet complete, but before i move forward, the name resolution code (in namesys) needs some critiquing. There are also a decent number of bugfixes in this branch that i ran into while trying to get the code to a point where i could test ipns.
does this mean that if I keep publishing then it will never actually publish? (not sure if that would ever be the case or what we would want to do then-- just an observation)
