Convert Tabs -> Spaces and Removed trailing whitespace from effectlib

This was done to make syncing the effectlib shaders in 3D Studio with
the effectlib shaders in the 2.0 runtime where they had already been
sanitized.  This makes the diffing process easier, and will also bring
things into line with the Qt coding standard.
