Ignore temporary objects in navigation pane

If you delete certain objects from the navigation pane and export source immediately afterwards, you may find some temporary objects still listed in the navigation pane, prefixed by `~`. These are removed automatically by Access when the pane is refreshed, so there is no need to export these items to the source file.
