Changes to GML 2 and 3. GML 3 now supports gml:Curve, gml:Surface, and the multis - with options to write the deprecated elements. Now reading boundedBy on features as geometry.bounds. Corrected lowerCorner and upperCorner elements. Added ability to build without the old gml parser. r=ahocevar,adube (closes #1918)
