[Qt] Windowed netscape plugins don't work with QGraphicsWebView on Symbian

STEPS TO REPRODUCE:
1. Load the sample plugin in a QGraphicsWebView
2. Observe the poor rendering

Is this bug really only for Symbian ?

That would make sense. At the time that we implemented Netscape Plugins for Symbian, QGraphicsWebView was under development and there was no API for getting the plugin's parent. I have left a FIXME in PluginViewSymbian.cpp about that.

Yael, can you verify that this bug still exists?

We don't have the plugin available for testing.

Yes, this is still a problem. Abhinav is working on a fix for it.

[Yael]

Agreed with Abhinav that I will fix this.

m_proxy does not need to be a member of PluginContainerSymbian; same with m_parent (in already landed code).

Calling setParent() in platformStart() would eliminate the need to pass in both the parent and the proxy to the PluginContainerSymbian constructor and in would - my view - make the code more readable.

Patch v2

Wrap a proxy widget around PluginSymbianContainer.
Some minor changes in using QPageClient API, due to the changes that were introduced in QPageClient after Symbian plugins implementation was done.
