Subject: [PATCH] Move name resolution of inversed dependencies to HMR server

Summary:Name resolution of inversed dependencies used to happen in node-haste, but that makes it difficult switiching to numeric module IDs.
This moves the name resolution to the HMR server in order to be able to change the logic more easily.

node-haste 2.9.0 provides a `Map` of modules to `Set`s that contain the modules that depend on the key.
