Fix use of missing properties in UI after game engine removal.

Finish use-after-free in workbench code.

GHash should probably not own the data itself, but that's other question
to be fixed later, at least this fixes the crash.

Solution by @fclem, thanks!

Code cleanup

Merge branch 'blender2.8' of git.blender.org:blender into blender2.8

Workbench: Option to use Object color

- added `object_color_type` where the user can set if the collection
determines the color, or the object will be used for the color.
Implemented it as an enum as later this can have a random color option.
- moved OB_LIGHTING_* to DNA_view3d_types and renamed it.
- Fixed some DRY in workbench_materials.c. Can remove more DRY's but
will need to discuss the responsibility of the workbench engine as it
might become part of the eevee renderer.

BMesh: Add back call to finish operator

Was commented in multi-edit patch, finish is needed to free memory.
