Fix Label colors in popups

Fix: use click style if a pie was spawned by release or click event

Manipulator: remove names

They weren't used anywhere,
both C & Py manipulators better assign to vars (no lookup needed).

stub update

Cleanup: Py3.7x warning

Cleanup: remove check for old GCC&PPC

Merge branch 'master' into blender2.8

Minor template code patch. (objectHitList =/= hitObjectList)

The Blender text editor's built in python template "Gamelogic" has a reference near the bottom to "objectHitList" as an alleged attribute to the KX_TouchSensor. This name is incorrect, it's correct name is "hitObjectList."

Attempting to access the suggested objectHitList returns error...
```
AttributeError: 'KX_TouchSensor' object has no attribute 'objectHitList'
```

The provided diff corrects this minor error.

Fix crash in recent changes to instancing

Registrable classes already handled their own instancing,
changes to enable instancing everywhere conflicted.

Last commit broke WITH_PYTHON_SAFETY

Re-enable BPY_id_release call with thats enabled.

BPY_id_release was a nop, use RNA invalidate directly

Fix T52186: Crash on bevel

bContext is not always available in transform, so need to use explicit
scene and scene layer to create evaluation context from.

CLeanup: Use utility function in BKE

Depsgraph: Add utility function to initialize evaluation context from scene and layer

Cleanup, line wraps

Initialize time for evaluation context when creating from bContext

Fix T52176: Bevel doesn't correctly work with default empty Vgroup.

`defvert_array_find_weight_safe()` was confusing 'invalid vgroup' and
'valid but totally empty vgroup' cases.

Note that this also affected at least ShrinkWrap and SimpleDeform
modifiers.

PyAPI: Store PyInstances for ID's

This means once an ID is created,
it will keep using the same PyObject instance.

This has some advantages:
- Avoids unnecessary re-creation of instances on UI poll / redraw.
- Accessing free'd ID's gives an exception instead of crashing.
(long standing annoyance!, though this only applies to ID's
and not yet other data that uses the ID's - vertices for eg).
- Allows using instance comparison (a little faster).

Note that the instances won't be kept between undo.

PyAPI: Fix for instancing (Blender owns a reference)

Also set newly created values to the instance pointer.

Manipulator: only check for highlight once

Was doing 2x lookups which is OK for click-select
but this runs on mouse-move and can become slow.

May enable this again if highlighting logic changes.

Also scale hotspot by pixelsize.
