Echo JS 0.11.0

I disagree, but I'm the author.  Registries are a pretty common problem across many codebases I've worked on, not just CanJS.  It talks about the 3 main ways of dealing with registries:

1.  Eliminate them, and make the user pass everything along.
2.  Reduce the API of the registry.
3.  Make it impossible to have multiple registries.
