Revert "UI: Add 7 new community themes"

This reverts commit d89e5fcaef5135360716053a43c4676508eaf5ef.

This was meant to be committed to the add-ons repo.

Fix Cycles standalone and tests build

Tests: add OpenVDB volume tests

Fix build with OpenVDB disabled

Merge branch 'master' into new-object-types

Volumes: add render settings for volume datablock

* Space: volume density and step size in object or world space
* Step Size: override automatic step size
* Clipping: values below this are ignored for tighter volume bounds

Cycles: change volume step size controls, auto adjust based on voxel size

By default it will now set the step size to the voxel size for smoke and
volume objects, and 1/10th the bounding box for procedural volume shaders.

New settings are:
* Scene render/preview step rate: to globally adjust detail and performance
* Material step rate: multiplied with auto detected per-object step size
* World step size: distance to steo for world shader
