Fix for issue 5 ("Page link dialog remembers last-selected link"):

The page link selector would look at the _initially_selected_nameless_uri member of the dialog to determine the default item to select. But, this variable was set in UI.Page_Link_Dialog._load_finder(), if a new link was being created, this function would not be called. Because _initially_selected_nameless_uri was not being re-set anywhere else, the initial selection would be the link that was edited last.

This instance variable (as well as _initially_selected_name) are now set to null in the dialog's init method, eliminating the problem.
