Remove some files restored in Game Engine

Most likely was caused by bad resolution of recent merge conflict.

Merge branch 'blender2.8' into greasepencil-object

Fix T59483: Grease Pencil Additive Drawing mode doesn't work with shapes

Add missing RNA type for hair brush.

Add missing padding in hair edit settings.

Eevee: Change Bent normal calculation

This changes the bent normal effect to be a bit more subtle.
I also tuned down the bent normal blending factor so mesh faceted look may
appear more in occluded regions. this is to increase the fidelity of the
indirect lighting. This blending might be a parameter in the future.

Based the calculation on "Bent Normals and Cones in Screen-space"
by O. Klehm, T. Ritschel, E. Eisemann, H.-P. Seidel

GPU: Add Intel HD Graphics 530 to the list of buggy intel gpus

Workbench: Use int to fix compilation issues on certain platform

Context: add objects_in_mode(_unique_data)

Needed for Python to easily support multi-object edit/pose modes.

Merge branch 'master' into blender2.8

Cleanup: use 'tool_settings' name everywhere in UI scripts

Context: remove active_gpencil_brush

We don't have this for other painting modes,
no need for a special case here.

Theme: use grey for blender_light inactive menu text

There wasn't enough difference between labels and menu item text which
could be selected.

Theme: use black for blender_light view-overlay

Cursor axes & transform guide contrasting w/ background was too low.

3D View: empty image option to show front/back

Only back was possible.

DNA: clear / remove deprecated flags

- Clear deprecated flags for ID's:
Scene, Sequence, World, Object & Mesh.
- Clear deprecated flags for Spaces: outliner, 3D view & image.
- Remove unused `Mesh.drawflag`
- Remove unused `USER_ALLWINCODECS`, `USER_MMB_PASTE`.
- Remove `V3D_SOLID_TEX` & `V3D_ZBUF_SELECT` - used in a few areas.
- Flip `Object.empty_image_visibility_flag`
(avoids do-version on each new flag)
- Rename 'Backside' -> 'Back' in context of drawing - showing 'Back'
makes sense.

Merge branch 'master' into blende2.8

Use subpanels for User Interface theme options

The widget color subpanels are dynamically generated.

Cleanup: use bit-shifted flag definitions in DNA
