Fix problem with preview for not visible materials

The preview must be generated with the color enabled and not checking the current scene settings. If we don't do this, the preview is empty for these materials.

Cleanup: moving shading type into View3DShading.

So all shading settings are in this struct and can be reused in the OpenGL
render engine.

UI: move specular light settings to Lights tab in user preferences.

Fix Python error removing studio lights in user preferences.

Fix inconsistent shade smooth naming in object and edit mode.

Merge branch 'master' into blender2.8

Fix T56003: Opening image files as movies in VSE crashes.

metadata loading code was assuming all videos in Blender were from
FFMPEG... added empty place-holders for other types too, we probably
could load some metadata from pictures or AVI files too!

World: Added 'Viewport Display' panel

The Properties->World tab had no Viewport Display panel. The world color
itself was hidden when the 'use_node_tree' was enabled.

Also renamed the World.horizon_color to World.color as it has nothing to
do with the color of the horizon (old BI feature)

UI: Single-column and flow layout for Scene properties

See D3532

UI: Minor fixes to separators on menus

Closes D3547

Object Mode: Add back object bound display

Implementing software result chaining. Do NOT compile!

Volume object datablock skeleton code.

This only adds Shift+A > Volume object and displays a list of grid names
in a specified VDB file. Branch pushed for reference if someone other than
me wants to pick up this project.

UI: Lamp -> Light for the object type visibility operators


Spotted in a live stream by Emilton Mendoza, thanks!

Fix (IRC-reported) wrong usercount handling of deprecated IPO datablocks.

versionning code would unref those twice... Reported by @�ergey on IRC, thanks!
