Properly exporting the transformFeatureInfo option

This was previously called getTransformFeatureInfo, which is a method instead of an option.  In addition, the generate-exports.py script does not properly export properties whose names appear on a different line than the @property annotation.  This makes the vector-layer.html, kml.html, and gpx.html examples work with the built lib.
