Purpose

Decreasing t-spline nodes weight during search so we will see nodes under a specific category at the top and later t-spline nodes.
I've changed the weight of Spline nodes at indexing time so when using criteria like "sphere" will show first the nodes under the Sphere category and later the T-Spline nodes which has the text "sphere" in the name. For implementing the expected behavior I've decreased the weight of the fields Description and SearchKeywords just for t-spline nodes.
