Web Manifest #83
Description
I think a great inclusion into this framework would be a web manifest file, with the ability to configure it through variables in theme-variables.css. Using the HubL variables to populate the manifest file.

One of the challenges I see is that .webmanifest and .json files cannot be created in the design manager. If browsers support .js we can use that instead, but we'll need to test it, I think some browsers may be okay with it but others might ignore it.
