QML examples documentation pages do not have breadcrumb links to QML examples index

For example, the "Image" example at http://doc.qt.nokia.com/4.7-snapshot/declarative-imageelements-image.html has a breadcrumbs trail of "Home > Examples > Image Elements: Image".

The breadcrumb trail should instead be "Home > Examples > QML Examples > Image Elements: Image" so that the user can find the QML examples index from an individual example page. This is what is implemented for other Qt examples, e.g. http://doc.qt.nokia.com/4.7-snapshot/itemviews-addressbook.html has a breadcrumb trail of "Home > Examples > Item Views Examples > Address Book Example", not "Home > Examples > Address Book Example".

Without this, users cannot find the QML examples index if they have navigated to an individual example page from the class documentation.
