Add new types of interpolation to CoordinateAnimation

A longitude animation can go in two directions West and East.
Current implementation is always using the shortest
animation path between two coordinates. Provide
setting to overload this behavior.

Add 'direction' setting to CoordianteAnimation. Implement
two new interpolators and provide new private
implementation derived form qquickpropertyanimation.
