Capability to work with sdo_geometry columns directly from activerecord models

I added GeoRuby objects support in my patches.
Utilizing this, the user can create/update a new point/line/polygon, directly from his/her Active Record programs.
For Example:
GpsPoint.create(name: 'New Location', location: Point.from_x_y(23,43))

If you found my changes suitable and you needed additional information, please let me know.

Thanks,
