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.
should just be:

```go
fmt.Fprintf(out, "%s\n", res)
```

All our outputs should be consumable by other tools.
