Imported WebKit commit 0dc6cd75e1d4836eaffbb520be96fac4847cc9d2 (http://svn.webkit.org/repository/webkit/trunk@131300)
WebKit update which introduces the QtWebKitWidgets module that contains the WK1 widgets based API. (In fact it renames QtWebKit to QtWebKitWidgets while we're working on completing the entire split as part of https://bugs.webkit.org/show_bug.cgi?id=99314
