Add sound extension

[softedco]

As suggested in #92
Playing sound from device didn't make it there because chrome blocks it.

is it possible to add "play sound from url until done" ?

Yes

Change this to use Scratch's AudioContext (Scratch.vm.runtime.audioEngine.audioContext) instead of plain Audio elements. I think there's something like a "media element source". Otherwise this won't be able to reliably play audio in browsers that have autoplay disabled.

See above

Made some changes:

• It will first try to play the sound using Scratch's audio engine, which means it'll integrate with volume, pitch, pan left/right, etc.
• If the sound can't be played that way (most likely because the URL does not support CORS), it will instead just use an <audio> element, like the original version.

Is it possible to add "pause [url]" ？

Is it possible to add "pause [url]" ？

From the audio element it is, but I don't know if it is possible with the audioEngine.

[GarboMuffin]

It will be possible in audio engine, just a good bit more annoying

aaaa

[GarboMuffin]

We'll do pausing later

[GarboMuffin]

Whoever wants pausing: Open a new issue and describe which exact blocks you would like. There's a lot of ways this could be done and I don't want to have to change it later. Also less likely to be forgotten that way.
