Reviewed by Yury Semikhatsky.

Source/WebCore:

Scroll and selection change handling is now delegated from TextViewer to SourceFrame.
SourceFrame now dispatches ScrollChanged and SelectionChanged events.
TabbedEditorContainer now saves scroll and selection information together
with the url history and restores scroll and selection on resource opening.
