Save
This menu item saves the information about a loaded image.
It does not save the image itself, since the HotSpot editor does
not need to change the image file.
If the image has the name (filename).(extension) the properties
filename saved is (filename).DBHotSpotGroup.
The information saved is all relevant information about the HotSpot
areas. This information is automatically loaded next time the image
is beeing opened.
