Ability to output X3D using GeoCoordinates

[robe]

This would be another proto version of ST_AsX3D that takes true/false boolean whether to output coordinates in GeoCoordinate? instead of standard X3D coordinates.

Of course it will need to have a known SRID. For starters just going to transform to GD (WGS 84 lon lat) (will not support the UTM ones yet since that would require mapping to their naming)

Hope to get this in in PostGIS 2.0, but might have to wait till 2.1.
