Message:

Added new virtual reseveElements, setElement, getElment and addElement methods to DrawElements?
to make is easier to write code that can work on DrawElementUByte, UShort or UInt.

Changed the osgTerrain::GeometryTechnique? so that it automatically chooses
the use of DrawElementUShort or DrawElementsUInt accordining to the size of the tile.
