When starting to edit a new dive location, create a marker at the current map center instead of zooming out and centering on the 0,0 coordinate. This will help (and speed up) a lot the edition, if the user needs to add numerous dive markers at a specific location close to each other. refs #754 Signed-off-by: Lubomir I.
