Added ray picking functionality via RayPickAction. Added unprojection

functionality to Camera class. Added Shape and TriangleBasedShape as
superclasses in the node hierarchy. Added TriangleCallback mechanism
for iterating vertices of triangles and PrimitiveVertex to represent
all data associated with a given vertex.  Made Actions keep track of
the path through the scene graph they are currently on. Added
RayTriangleIntersection based on paper from Journal of Graphics
Tools. Augmented DisplayShelf demo with click-selection of movie
titles and reduced priority of background loading thread to avoid
rendering hiccups.
