[webkit-qt] API proposal for handling (some) hybrid use cases

This is exactly along the lines of my thinking. Good work!

I do have some comments.

Maybe instead, we should allow
navigator.postMessage, and add it as a proposal to HTML5 window messaging? It just feels more natural.

Also, we should be clear about what the origin fields should have in the message. There might be a security issue, since iframes might post messages to the parent window pretending to be the navigator. 
I'm thinking that messages to/from the UI container should always have a navigator:// URL to their origin, and in WebKit we can make sure those are not faked.

No'am
