Re: [web-bluetooth] No popup to choose device

`referringDevice` isn't implemented yet, and when it is, that'll be user-directed scans, not page-directed scans. There will be a [scanning API](https://webbluetoothcg.github.io/web-bluetooth/scanning.html), but again, to communicate with a discovered device will take 2 permission prompts.

Chrome requires the two clicks from `requestDevice()` because it's pretty dangerous for users to grant access to a BT device, and we want to give them as much chance as possible to realize what they're doing. Even this level of concern still worries some people: http://www.tomshardware.com/news/google-web-bluetooth-webusb-apis,33589.html. However, another browser could certainly decide to use a different UI that lets the user select the first matching device with a single click.
