Shape and Point TemplateProviders hints improvements

The current hints for points and maps in the type selector on the creation page refer to the "Create" action (e.g. "Create a point for map") , rather to a plain description, like the other template providers. What about rephrasing them as "Geographical point with a latitude and a longitude", and "Geometrical shape: polyline, rectangle, circle" (it should be kept short enough for one line max though).
