Parse KML extrude and altitudeMode from multi geometries

Browse Source 
Handle MultiPoint, MultiLineString, MultiPolygon.
LinearRing properties are not handled.

An 'extrude' boolean array property is set in the geometry properties.
An 'altitudeMode' string array property is set in the geometry properties.
