RNA: remove manipulator arg

There is no need since 'self' is the manipulator.
(was left in from these callbacks being attached to manipulator-group).

RNA wrap wmManipulator.setup callback

Merge branch '28' into custom-manipulators

do not check constraint islands in case constraint collision is activated (allow self collision)

Added 2D shape topology detection, first silhouette geometry gets created. Use with alt+leftclick within sculpting mode.
--Experimental/Broken--

check for availability of "constraint_type" in DNA struct, if not there set default value "fixed"

Final Implementation of method one with few editing

added constraint type setting for FM constraints

previously there was only a cluster constraint setting

added Dissolve plastic constraints option, only relevant for external mode

added particle velocity scaling

Add same new ID freeing API as copying one.

Idea is the same, looks like it will be a tad simpler than with copy
though, since we should not need to change each ID type freeing func, as
ID usercount handling is done in main BKE_library code (would like to do
that for copy as well, but it's not that simple).

On second thought, avoid adding new stuff to ID.

We can extend ID->tag and store there our few alloc-related tags.

Fleshing a bit new copy logic (using Object datablock as Guinea pig).

Layout initial ideas/code structure of new ID copying.

Merge branch 'blender2.8' into greasepencil-object

Remove upper limit of stroke thickness

Merge branch '28' into custom-manipulators

Missed in recent removal of face-maps

Very minor edit (2.8 sync)

Remove face-map / armature integration

Since we're unlikely to use this, it's tedious to keep so many
differences from 'blender2.8' branch.

Currently the only difference between this
branch and 2.8 is RNA/Python work-in-progress integration.
