Trigger layout after resizing the FrameView.

There are problems with QGLWidget based web plugins due to the fact
that WebKit forces us to relayout during paint events, which in turn
might resize widgets, causing the shared backing store's QImages to
be corrupted and hence causing crashed.

This patch triggers a layout upon resizing the FrameView, which reduces
the likely hood of resizing plugins during a subsequent paintEvent.

Add padding objects for classes with netscape plugin api conditionals.

When building with the Visual Studio Compiler on windows, we are facing
some problems because objects that are shared between WebKit1 and
WebKit2 have different memory maps for inlined accessors because the
Netscape Plugin API had to be disabled for the WebKit2 API on Windows
in the new snapshot for Qt 5.2.

This caused plugins not to be loaded because the wrong values for the
mime types and urls are returned and might lead to all kinds of bugs and
quirks.

This patch adds dummy pointers / data structures for the parts of the
build that do not have the Netscape Plugin API enabled.

Fix crash when converting QObjectList

We were passing on a PassRefPtr to multiple lower calls, since any
conversion from a PassRefPtr to a RefPtr will reset the PassRefPtr to
null, it should not be used for multiple calls.
