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.
i beleive it actually defaults to one, i was bumping it to two just for my own sanity. (let me know if im wrong)
