Workbench: Remove warning

When in forward rendering and Object outline was disabled every render
call created one console warning (uniform objectId not found)

this commit removes this warning

Revert "Objects: when active object gets hidden, make it inactive."

This reverts commit fec97ec949, it's useful to be able to edit object
properties for hidden objects. The issue with mode locking that this
was meant to solve will be handled in another way.

Merge branch 'master' into blender2.8

T55570: Moved Texture drawtype as to shading popover

the use of the texture drawtype is limited. so who should we have it
this prominent on the screen. By adding it as a shading.color_type
option we should save some screenspace.

UI: preference for developer extras

Currently only used for "Edit Source" feature.

Fix T55568: second click event ignored

Double-click handling caused the second click to be ignored
for keymaps that only handle click.

Python/BLF: add blf.color(r, g, b, a) method.

This is needed now that glColor() no longer works.

Fix T55573: Mode rotate on local axis crashes

UI: Single column for Rigid Body World

Fix Cycles CUDA render errors with CUDA 9.2.

Work around what might be a compiler bug.

Studiolight: Calculation of irradiance buffer

The calculation of the irradiance buffer was slow. Now it is only
calculated when it is being used (background_alpha > 0.0)
this solves the freeze when switching to LookDev mode.

Also changed the default calculation to use the Spherical Harmonics
calculation. This is able to generate the irradiance buffer fast, but is
less accurate. As the irradiance buffer is only used for visual
guidance speed is more important than accuracy.

Added compile directive to switch between the implementations.
(see STUDIOLIGHT_IRRADIANCE_METHOD)

Disabled caching the irradiance buffer when
STUDIOLIGHT_IRRADIANCE_METHOD_SPHERICAL_HARMONICS is used as it is not
needed.
