Robert Osfield ebf3804c84 From Sebastien Messerschmidt, "attached you'll find a patch for the shp-plugin.
I've spotted huge memory leaks int ShapeParser and fixed them.
Also, there was a missing destructor (PolygonM) and a missing member initialization (PolygonZ)
Would be nice if someone could test the changes.

To release the memory just if no reading error happened (and therefore the arrays would be valid) I've added an macro to release and reset the pointers at once. I'm not using macros myself very often as I don't like them, but I think it doesn't hurt in this code.
