Summary: This is the next incremental step to rewrite node-haste. I apologize for the size of this diff but there is really no smaller way to do this. The current architecture passes a single file watcher instance into many classes that each subscribe to file changes. It's really hard to keep track of this. The new implementation reduces the listeners to two (will eventually be just one!) - one in DependencyGraph and one in it's parent's parent's parent (ugh! This doesn't make any sense). This should make it much more straightforward to understand what happens when a file changes. I was able to remove a bunch of tests because jest's watcher takes care of things like ignore patterns. Some of the tests were specifically testing for whether the change events were invoked and they are now much more straightforward as well by manually invoking the `processFileChange` methods.
