Added filer - I think the winner of my VFS effort.

MakeDrive uses it, http://blog.humphd.org/introducing-makedrive/ it is
part of mozilla’s tooling. I still want an abstraction layer to support
many file systems, but rather than home cooking something here, I want
that abstraction to be Node’s API. See, I want node’s FS API to be the
OS-VFS API. At this point it is not even an exercise in humility, this
morning I was meditating over
https://github.com/substack/http-browserify and given that node-webkit
uses node-like API, I think it is fairly OK to put some eggs in this
basket :chicken:
