Audio only WP YouTube Lyte broken, fix expected

[Update: this indeed got fixed with 1.1.4]
So audio-only embedding is broken due to YouTube enforcing the minimum embedded player size that has been added to the TOS recently. I’m working on a fix for this, expect 1.1.4 soon. And if you’re impatient (or want to help), you can always download the development tar-ball here.
