If there's no data for the widget "Visites par fuseau horaire du serveur", the informative string "Aucune donne pour ce graphique" is so big that it's cut, so we can't read it completely. See the attached screen shot.
For consistency, we should use the #emptyDatatable div. Currently, the title is displayed by the Flash widget (instead of as HTML).
fixes #1020 - only the last chart added to the dashboard can be saved locally (using the right-click pop-up menu to "Save Image Locally"); the footer icon link worked properly
fixes #947 - truncated translation string in Flash widget when "no data"; this is now styled consistently with "no data" for tables and tag clouds
