Feature request: Proper queue support

[YouKnowBlom]

Relevant doc: https://developers.google.com/cast/docs/web_receiver/queueing

We can get the playbackInfo of multiple items and populate the queue by sending multiple ids to {{baseUrl}}/Items?. While not an optimal solution since we're sending deviceprofile when requesting playbackInfo, I don't think the capabilities of the cast device will change often.
