S1 Demo Chrome Extension

 This extension adds a small phone icon in the omnibar if you are on a current salesforce.com instance.  Clicking the phone icon will open a window with roughly the same resolution as an iPhone 5 to the one/one.app for that Salesforce instance.  Handy for doing quick demos of Salesforce1 mobile applications on a desktop browser.

UPDATE: It appears in Summer 16 Lightning may have to be enabled to run Salesforce1 in a browser.  I believe it only needs to be enabled on the org/instance level.  

Im looking into this, but if it is determined at the org level it is out of my control.
