Merge branch 'master' into soc-2019-bevel-profiles

Updated debug orientation drawing.

This will make it easier to debug issues with the orientation calculations.
It's now easier to tell which edge_half each marked profile start boundvert belongs to.

Profile Widget added to global ToolSettings struct and edit mode bevel tool.

Now the same profile widget should be accessible everywhere, so the changes
should carry over from one call to the next.

The tool settings for bevel are now drawn in a custom callback which also enables
some fancier hiding of properties when they're not being used, which I've also
taken advantage of in this commit.

There are still a couple bugs with the new redo panel but the bulk of the work is
finished for making the bevel tool work with custom profiles.

GPencil: Add "Self Overlap" parameter to materials to disable Stencil

This parameter was removed in 2.80 and we decided to back again, but now is inverted.

This is to solve the fixed limit defined before.
