Previously GAE Channel callbacks would be handled by JS string-encoding the payload into a URL. Unfortunately this is limited to the (undocumented, silently problematic) maximum URL length UIWebView supports. Replaced this scheme by a notification from JS to ObjC and a getter from ObjC to JS (which happens out-of-line to avoid worrying about UIWebView's re-entrancy, or lack thereof). Part of this change also moved from a combination of: JSON, URL-escaping, and ad-hoc :-separated values to simply JSON. Also incidentally: - Removed outdated TODO about onRenegotiationNeeded, which is unneeded - Move handling of PeerConnection callbacks to the main queue to avoid having to think about concurrency too hard. - Replaced a bunch of NSOrderedSame with isEqualToString for clearer code and not having to worry about the fact that [nil compare:@"foo"]==NSOrderedSame is always true (yay ObjC!). - Auto-scroll messages view.
