UI: fullstop at end of tooltips

Allows for multiple sentences not to look strange.
Convention not to include in RNA remains.

Layer collection enable flag

Right now this is exposed in the outliner, though all this
(visible/selectable/enable) should be moved to a new panel soon.

This removes objects from the depsgraph when the collection is disabled.

It allows you to "hide" lamps but still having them lighting the scene.
Same for light probes and other support objects.

Pending tasks:

* Have depsgraph to include invisible objects in the DEG_OBJECTS_ITER, and
then have Eevee and other engines to make a distinction between an
invisible and a visible object.

(for example, we probably want invisible objects to not show in the
viewport, but cast shadows and show up in light probes).

* Change how we evaluate collection settings so that an invisible
collection can force an object to be invisible.

deps build: correct sndfile fix

Manipulator: fix visibility check w/ 2-axis planes

Cleanup: move 3d manipulators into an array

Merge branch 'master' into blender2.8

BLI_polyfill2d_test: script to generate test data

deps build: fix sndfile building on macOS

macOS: use python version 3.6 when building blender

deps build: bump Python to 3.6.2 and Numpy to 1.13.1

Correct test ifdef in polyfill

Fix T52834: Polyfill2D fails with co-linear edges

BLI_polyfill2d_test: add test for T52834

Commented since it currently fails.

BLI_polyfill2d_test: Try flipped x/y axis

In T52834 this makes a difference.

Merge branch 'master' into blender2.8

transform_snap_object: simplify IGNORE_BEHIND_RAY

`depth_get` is called in most of the time. So not worth going through so many conditions
