Rename Page.widget -> Page.page_widget; it is now an EConfigPage instead

* e-multi-config-dialog.c: Rename Page.widget -> Page.page_widget;
it is now an EConfigPage instead of just a GtkWidget.  Add
`num_unapplied' to EMultiConfigDialogPrivate.  Derive from
GnomeDialog, not GtkWindow.
(update_buttons): New function to update the sensitiveness of the
buttons according to whether all the settings have been applied or
not.
(page_new): Likewise.
(create_page_container): Renamed from `create_page_widget'.
(init): Add Apply/OK/Cancel buttons to the dialog.  Init
->num_unapplied to zero.
(page_changed_callback): New, callback for the page's "changed"
signal.
(e_multi_config_dialog_add_page): Connect the callback, update
->num_unapplied, update the buttons by calling `update_buttons'.
(ok): New function for handling the OK button.
(apply): New function for handling the Apply button.
(cancel): New function for handling the Cancel button.
(impl_clicked): Implementation for the GnomeDialog's ::clicked
signal.
(class_init): Install.

* test-multi-config-dialog.c (add_pages): Update to use
EConfigPages instead of plain GtkWidgets.

* e-multi-config-dialog.c, e-multi-config-dialog.h: Derive from
GnomeDialog, not GtkWindow.

* e-config-page.c: New.
* e-config-page.h: New.
