Narrative

As a developer, I can utilize the latest features of Knockout, so that I can make the world a better place.

Acceptance Criteria

All existing tests should pass.

Analysis

Update knockout library to latest version

I tried to set “ko.options.deferUpdates = true” in shell.js but that caused 61+ unit test to fail because notifications where being fired off at different times then they currently are.  

Per Tom let’s just upgrade to Knockout v3.4.1 and get any benefits from that and turn on deferedUpdates later.

Note that there was an error generated in the unit tests after initially upgrading but was fixed based on a comment by Michael Best  (knockout/knockout#1858 (comment))
