WIP: First step to remove Palettes from Draw Manager

Still is not working.

Cleanup: Rename material index field

Now the name is equal to other Blender areas.

WIP: Start the working in operators

- Delete Material->Strokes
- Move material in the list->Reasign Strokes

Remove Palette panels and fix write/read bugs

Now the panels works with materials but still the drawing engine and operators is using the old palettes.

Fix error reading materials

The link materials section was missing.

WIP: More work converting to materials

There is a problem with the loading of converted files.

The conversion of Hero data is correct, but something is still missing.

Removed unnecessary free

Merge remote-tracking branch 'origin/blender2.8' into temp-modifier-rm-cddm

Copy CDDM to allow freeing the mesh

Don't use MEM_SAFE_FREE as it causes warnings

Remove debug stuff

Always get the vertex coordinates from the original mesh

Get from original instead of CoW copy, otherwise there is the risk of
deforming already-deformed coordinates.

Some debugging going on here

Precious attempt at being ok

Ported Build modifier to use Mesh instead of DerivedMesh.

More work to prepare material conversion

Doing RNA stuff and preparing for convert Hero files

Fix crash when no mesh in passed to deform functions

Create new fields in material for moving palettecolor

Fix: ASAN-related crash when scaling points in editmode

Merge branch 'blender2.8' into greasepencil-object
