GP: Rename Canvas Grid to Canvas

Redefine the Relative custom B-Bone handle type to be more reasonable.

Specifically, it should always use the position of the custom handle
bone head, even when affecting the handle at the tail of the main bone,
and shouldn't apply the special handling for joining two B-Bones.

This handle type was unusably broken before a bug fix included in
recent changes, so it should be safe to break backward compatibility.

GP: Remove decoration in Viewport Display panels

GP: Cleanup grid RNA settings moving to separated struct

Cleanup: capitalize runtime in struct name

Context: add uv_sculpt_object

While this may be temporary, it avoids copy-pasting these
checks in Python code.

GP: Cleanup names and code

Cleanup: style

UI: show uv sculpt options in topbar & toolsettings

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

Merge remote-tracking branch 'origin/master' into blender2.8

Cleanup: remove gpencil label from common code path

Tool System: prepare for showing non 3D view tools

RNA: add access to tool mode

Tool System: initial support for UV-sculpt

This currently conflicts with the UV-sculpt toggle being manually set,
ideally this would work more like other paint modes in Blender.

Cleanup: use PyModule_AddIntConstant

Fix invalid flag passed to mesh batch dirty tag
