artemp/trac2github — Issue #574: Null shapes

According to shape file documentation :

"A shape type of 0 indicates a null shape, with no geometric data for the shape. Each feature type (point, line, polygon, etc.) supports nullsit is valid to have points and null points in the same shapefile. Often null shapes are place holders; they are used during shapefile creation and are populated with geometric data soon after they are created."

Currently null shapes are not handled correctly unless .index (index file) is present.
