Improve rekonq WebKit settings

This patch changes WebKit Settings window removing the "unuseful"
stuffs and adding some news like WebGL or Frame Flattening
(probably useful also on netbook).
It also redesign/clean up the settings widget

Let us require QtWebKit 2.2.x, hence Qt 4.8.0 at least until someone
will explain me how I can check QtWebKit version number with cmake...
