selection-change is not fired for "blur"

[jbrowning]

Clicking outside of a focused Quill editor does not trigger a "selection-change" event.

Steps for Reproduction

1. Visit https://jsfiddle.net/jeffb/cpneefcx/
2. Focus the editor (note the alert and console log)
3. Click anywhere outside the editor

Expected behavior: A "selection-change" event should be emitted and an alert should be displayed. You can see this expected behavior in action for 0.20.1 here.

Actual behavior: No "selection-change" event is emitted.

Platforms: Chrome 50.0.2661.102 (64-bit) on MacOS 10.11.4

Version: 1.0.0-beta.1

Also noticed (might be related), "selection-change" does not fire when re-focusing the editor and placing the cursor where it was before. Again, different behavior in 0.20.1.
