(svn r9111) -Feature: [OSX] mighty mice and touchpads can now scroll the map (in all directions)
It has to be enabled first (in patches->interface) first and this will disable scrollwheel zooming
Note: patch setting "Map scrollwheel speed" might need to be changed since the "correct" setting
appears to depend on what kind of mouse is in use (mighty mouse or touchpad)
