5.11.0 Release Candidate

This is the first publication the new Kiosk app update notification system. It will be used any time a new release for Kiosk is ready for review. Generally, this will be 1 week prior to the scheduled publication date to give some time to test the update with existing installations.

The v5.11.0 release candidate is ready for review and testing: https://github.com/matt-cook/kiosk/pull/208

It is currently scheduled for publication on April 5, 2017.

To install, you'll need to download the un-packaged v5.11.0 release here: https://github.com/matt-cook/kiosk/archive/v5.11.0.zip then install the `src` folder as an "unpacked extension", as described here: https://developer.chrome.com/extensions/getstarted#unpacked

Please do let me know if you run into any errors by posting a comment on the PR or emailing me directly. I'm happy to help resolve them and/or push back the release date as needed to accommodate.
