This updates startup file loading so BIOS and image downloads are kicked off together instead of waiting for each previous file to finish. Each file still updates the same settings entry and progress event metadata, but startup no longer serializes independent network requests.

Tested with node --check src/browser/starter.js.

Closes #823

Thanks!

The progress handler also needs to be updated to handle multiple simultaneous progress events.

You can test this by setting disable cache and throttling to 3G in chromium's dev tools network tab.
