dashboard: Use the non-translated versions of pane and dashlet names for storage

This is a dirty quick fix. And calling it *quick* is already an overstatement.
Of course, it's also a breaking change, as **all** non-english users need to
update their dashboard.ini after this change.

Oh, and don't dare to move this over to the new dashboards!
