Ugly Hacky Fix: Clear Loc/Rot/Scale + Autokey now works for bones

This is a hacky fix so that animators can use this tool again with autokey enabled
(which they do all the time). The issue here is that the tool writes the new (0)
values to the original data, but insertkey now reads from evaluated data (so that
keying interpolated values works). However, the cleared values do not get re-evaluated
or flushed before insertkey gets to it (via auto keying), meaning that the wrong values
get keyed.

There may be better solutions for this, but for now, this is the simplest fix that
I can get working.

sparse volumes initial commit

Cleanup: rename color members in gpencil style

It reads like a bug to store alpha in variables named 'rgb'

Also remove some redundant casts.

EEVEE: lookdev default materials

Cleanup: remove gp_ prefix from variable names

These are already in a grease pencil struct.

Fix T55231: Setting bone.select from RNA didn't tag for copy on write

This was causing problems with addons such as the Selection Sets addon used
in studio by the animators.

CoW: Skip pointers that are used in Lattice edit mode.

Cleanup: Fix typo: updata -> update

CoW: Skip used pointers in MetaBall edit mode.

CoW: Skip pointers used in Text edit mode.

Tool System: workaround psys cursor conflict

This needs to be solved properly, for now add cursor-click tool
which can co-exist w/ particle paint.

RNA: re-enable property notifiers

While these will be removed eventually,
it makes tracking down COW buts a hassle.

Depsgraph: preserve memory caches for particles when creating Copy-on-Write

Solves issue with particle memory cache ignored.

Thanks Bastien for review!

Merge branch 'blender2.8' into greasepencil-object

Workbench: Fix uninitialized variable usage.

EEVEE: LookDev storage list wrongly used

Fix T55226: outliner glitch with item open/close, after recent optimization.

EEvEE: LookDev

Fix: Action/Graph editor UI's didn't update when channel properties were changed

More MessageBus-related silliness to resolve issue with toggling visibility/mute/locking
status of F-Curves/Groups/etc., as well as other things like modifying active keyframe's
values, or changing properties of F-Modifiers.

I've now ended up just whitelisting in the region subscribers all the animation-related
structs in RNA. But still, that may not be enough to deal with potential issues later
with the property sliders (shown per channel, optionally), which can come from anywhere.

(Spring bug)

UI: Option to layout properties in two columns

Needed for proposed alternate layout, see T54951.
