Add a page list widget to installer wizard

If an installer is configured with <WizardShowPageList> set to true
(default), a QListWidget set as a side widget for the wizard will be
shown. The list should indicate completed and incomplete pages and the
current wizard page. User navigation is not enabled in this change.

The page list should honor the visibility of individual pages and
update itself dynamically. In addition the visibility of a page in
page list widget can be set internally with setShowOnPageList() which
overrides other factors when hiding a page.

The page item title shown on the list can be set internally with
setPageListTitle() for the PackageManagerPage object, or the item can
alternatively use the normal page title and the object name.
