Goo Location Creep

I've been wrestling with the problem of defining the file locations where The Goo will look to stick things together. I first implemented a monolithic config file, but although this gives fine-grained control over where The Goo should look I often find myself stopping and adding new locations as I move into new areas of the filesystem - where possible I want to avoid this feeling of going backwards.

The idea is The Goo should faithfully follow behind, seamlessly helping you to stick stuff together. The solution is for The Goo to incrementally discover the locations you're interested in and remember them. So the more you traverse your filesystem the more Things become "associated".
