 First part of the clipContentsToViewport fix (introduce paint method, deprecate render) 

We had a quick round of API review with Matthias here at the DevDays and came
up with the following suggestions for changes:

* QWebFrame::clipContentsToViewport:

    1) Remove the property
    2) Deprecate QWebFrame::render()
    3) Introduce QWebFrame::paint(QWebFrame::PaintOptions opts =
QWebFrame::AllElements), so that one can for eaxmple call

    frame->paint(QWebFrame::Contents);
    frame->paint(QWebFrame::Contents | QWebFrame::ScrollBars);

Follow up patch will remove the clipContentsToViewport property

Might be worth considering making the numbers for the enum a bit bigger so that if you later want to add intermediate layers they can still have an id that reflects the stacking order. eg. 0x10, 0x20 etc. instead of 0x01, 0x02.
