Add "HiResolutionIconUrl" in manifest.xml by default

[martellaj]

Apparently having the HighResolutionIconUrl element is mandatory in submitting an Office Add-in. Might as well include that by default then.

Hmmm... I'm not seeing it in that link... searched for HighResolutionIconUrl

It was feedback I got when my app was reviewed. Maybe a bug in the content. I'll follow up when I get to the office.

OK I see it listed in the manifest schema but the schema does not say it is required... however i'll include it as it can't hurt.

It's included in a future update that I'll push from my fork: b1eae8f

Oops... pulling this out of task pane & content apps... can't find it in the Office Store requirements link you have above, but did find it here as being listed only for mail apps: https://msdn.microsoft.com/en-us/library/office/fp161044.aspx
