* call to <code>open()</code> will not return until the dialog closes, so this is the last chance

*
* @param shell The Shell to parent the dialog off of if it is not already created. May be <code>
* null</code> in which case the active workbench window will be used if available.
* @param preferencePageId The identifier of the preference page to open; may be <code>null</code>
* . If it is <code>null</code>, then the preference page is not selected or modified in any
* way.
* @param displayedIds The ids of the other pages to be displayed using the same filtering
* criterea as search. If this is <code>null</code>, then the all preference pages are shown.
* @param data Data that will be passed to all of the preference pages to be applied as specified
* within the page as they are created. If the data is <code>null</code> nothing will be
* called.
