Depending on GadgetRepo::singleton() to return a specific implementation is fragile. Pass each created/updated/deleted page to GadgetRepo::handlePageCreation/Update/Deletion() and let each specific implementation deal with it. Use LinkTarget to be TitleValue compatible for the future. Change-Id: Ibe2e26d12369a897c53757adf621926f62af7f7b
