Merge branch 'master' into soc-2018-hair-shader

Week 7 merge for this week's builds

Turned off clang warnings in third party includes.

The latest clang compiler (at least the one in Xcode 9.4.1) warns about the register keyword and macro expansions using defined().
Since these warnings come from third party code, we can't address them directly in Blender. Silencing them via #pramgas will
at least keep the warnings during a build down to the ones that are relevant to Blender code.

Merge branch 'greasepencil-object' into temp-greasepencil-vfx

Merge branch 'blender2.8' into greasepencil-object

WIP: Initial steps to implement VFX again

Fix crash with files saved with missing render slots.

UI: Use background color for reports

At the moment it's using a hardcoded gray color that conflicts with
themes using gray for the header text. Instead use a slightly brighter
background color to make it stand, yet still use a theme setting.
