09/12/2009 - Handle add to/remove from request list buttons for property blocks in pages
*/

Note: because a property may appear more than once in a page, we're using indexes rather that property id's for referencing properties!

Note: the class is instanciated only if request-list feature is used. Otherwise, only static methods are used by the request-make feature
