+ WebKitTestRunner needs layoutTestController.setWindowIsKey

+
+ Reviewed by Anders Carlsson.
+
+ Implement layoutTestController.setWindowIsKey() in WebKitTestRunner.
+ This sets a flag that the platform layer uses to indicate that
+ the window is the key window, which fixes focus ring drawing
+ in pixel results.
+
+ Also focus the web view when we get a 'didCommitLoad' for the main
+ frame, as DumpRenderTree does.
