Rename weight index field

This commit is a previous step to move the weights to MDeformVert and MDeformWeight

Pose Toolbar: Added Breakdowner/Push/Relax as separate tools

Currently all are stacked together, but perhaps if we don't get any other
tools in the meantime, it would make sense to have them separate.

Notes:
* No icons for now...
* There are some 2.8 bugs with the underlying operators (notably multi object)

Edit Armature Toolbar: Added some tools for "Shrink Fatten" (Alt-S) type bone transform tools

For fun, I tried adding some more edit armature tools to the toolbar to
check how this is all working. Icons are missing currently, but it's a
nice test.

Fix bone-size crash

Own regression from multi-object transform.

Remove some deprecated scene->gpd

Still some pending.

Merge branch 'master' into blender2.8

Cleanup: last spacetype enum name

Merge branch 'blender2.8' into greasepencil-object

Merge branch 'master' into blender2.8

Cleanup code

Cleanup: Define alpha field.

Fix inconsistent usercount handling of MaterialGPencilStyle.ima/.sima

Readfile was treating them as refcounted, RNA as user-one, and libquery
as not refcounted at all!

Full usercount makes more sense here, those images are used as 'real'
data for GP materials, not as temp setting of a brush!

Cleanup: Fix unused parameter warning.

Undo System: remove nested edit-mode undo calls

Regression in recent undo system changes,
This caused T55048.

When each mode had its own undo stack it was important
to initialize it when entering edit-mode.

Cleanup: fix error w/ const arg

Cleanup: Remove duplicate parameter (cont.)

Cleanup: Remove duplicate parameter

Fix texture space transform crash

Own regression from multi-object transform.

Fix T55061: Shadows were not updated during sclupting.
