Remove Frame.GetProperty/SetProperty deprecated methods from API docs. This methods are not implemented. I guess they are remainings from CEF 1 which ran using single process mode and getting/setting properties worked synchronously. But in CEF 3 which runs in multi-process mode you can do this only asynchronusly, you can use already implemented js<>py communication layer for that.
