Use HTML5 download instead of extension API
Benefits: - Cross browser solution (however only for relatively new browsers) - Doesn't need extra permission in Chrome If the browser doesn't suppor the download attribute, then a new tab will be opened with the exported data. Other changes: - Start the download only if the data is not empty (previously the download started anyway) - Reorder code in vapi-client.js for Safari, so unnecessary code doesn't run on extension pages
