Ported osg::Geometry across to supporting the aliasing of vertex, color and normal etc. calls to Vertex Attributes.

Browse Source 
Added support for automatic aliasing of vertex, normal, color etc. arrays to Vertex Attribute equivelants.

Added new osg::GLBeginEndAdapter class for runtime conversion from glBegin/glEnd codes to vertex arrray equivelants.

Added automatic shader source conversion from gl_ to osg_ builtins.
