StudioLight: Add a 4th light to adjust lighting

There was a bug due to non-aligned struct in the DNA that prevented us
to increase the size of the userdef light array.

Since the studio lights are now presets and stored in external files,
there is no need to keep backward compatibility with theses lights.

Remove the old array and create a new one.

Add blue tint light for specular.
