- removes storage of bounding box from QgsPointV2 (gives significant decrease in size of object) - more efficient calculation of bounding box for linestrings Additionally, this commit moves the bounding box invalidation to a virtual QgsAbstractGeometryV2::clearCache() method, so that other non-bounding box caches can also be cleared when the geometry is modified.
