Title: Extended equalityComparer support to dependentObservables

With this patch, dependentObservables only notify subscribers if their computed value has changed. Changes are detected with equalityComparer, just like with observables.

This was such a small change, I'm wondering if you have a good reason why dependentObservables must always notify subscribers. Thoughts?
