Gvr-unity-sdk: Daydream keyboard should support Physical keyboards

[RangerMauve]

Summary:
It would be nice if the GvrKeyboard could act like a standard way of doing any keyboard input including Bluetooth keyboards.

Steps to reproduce the issue:

1. Connect a bluetooth keyboard
2. Open a VR app like Chrome
3. Use either on-screen keyboard or physical keyboard to type

Workarounds:
Apps can manually add listeners for the keyboard APIs, but this would be duplicated effort and a lot of apps probably wouldn't even think to do it.

Honestly, this is really low priority for us. I don't think we'll get to it any time soon. Closing this.

[RangerMauve]

Would a PR be welcome for it?

[chaosemer]

Happy to take PRs! Please make sure it can be done in such a way that there's only one GvrKeyboard API to Unity apps that works in both cases.

[RangerMauve]

I was thinking the most basic thing that could be done would be to listen on the existing Keyboard APIs that Unity provides in order to add to the input buffer.

I'd have to see the PR to judge if it looks reasonable or not. The core idea certainly seems reasonable.

This is certainly doable as sample code, but I agree with you that avoiding the duplicate effort seems vauable.
