Switch LSNC to a new path value metric that test higher and has better path length resolution when paths are short.
Make the search trigger in Ducttape.c at least kind-of sane, so we only search when we don't alrady know a path to the destination node.
Try to refresh reach regardless of if we have a direct path or not, prevents bug where we have all 0-reach paths and never try to refresh any of them.
Search for new routes if we already know some but they're terrible.

some distributions ship node as nodejs
refreshReach is killing performance, yank it
