Fix assert opening file selector

Per view-layer collection visibility

We still control this in the viewport collections visibility menu. But
now we are actually changing the visibility of the collections, not of
the objects.

If a collection is indirectly invisible (because one of its parents are
invisible) we gray it out.

Also if you click directly in the collection names, it "isolates" the
collection by hiding all collections, and showing the direct parents and
all the children of the selected collection.

Development Note:

Right now I'm excluding the hidden collections from the depsgraph.
Thus the need for tagging relations to update.

If this proves to be too slow, we can change.

Outliner: Do not gray out empty collections

We can still have a special icon for them, but graying out is not the way to go.

Remove eye column from the outliner

To control per-viewlayer, per-object visiblity users should either use
the menu or the H shortcuts (H, Alt+H, Shift+H).

Following next will be to have proper per-viewlayer collection
visibility. This will replace the functionality currently at the
viewport collections visibility menu.

Correct error clearing runtime tool in recent commit

WM: remove tool initialization code

Area initialization handles these cases now.

WM: avoid re-initializing tools while resizing areas

Every update caused the gizmo to be recreated.

Fix tool not being initialized switching windows

RNA: disable animating sequence channel, lock

Scene: 3D cursor rotation wasn't initialized

Missing from last commit

Cleanup: remove unused app-template flag

Cleanup: style

Local View: Objects to be selected once back to regular view

They were already selected, but we needed to bump depsgraph.

Tool System: remove custom tool registration

API is not ready for beta (likely to change).

Transform: default to user-defined orientation

Previously we tried this but reverted (see 64d40c82c324)
because there wasn't a predictable set of keys to use global-space.

Now the keys are swapped:

- 'GX' always transforms in the user defined orientation.
- 'GXX' always transforms in global space.

As before 'GXXX' cycles back to disabling constraints.

This does have a down side that GXX won't be used for local-space
when the user has global space set.
Also, when global is the user-orientation, pressing GX and GXX
does the same thing.

Note: examples here use GX but could be any transform-mode/axis.

UI: Reduce amount of padding between VSE channels.

Print filepath in message when saving userprefs

Was just printing 'ok' on success.

Keymap: Change default spacebar action to play

This has been a contentious topic: Artists at the Blender-Studio prefer
this behavior, while the user community overwhelmingly prefers 2.7x
operator search. Previously this defaulted to accessing tools
(eg: Space-T activates transform.. Space-R rotate etc) which I still
believe is a better long term default - otherwise we don't have
efficient tool switching for a system we intend to make more use of,
nevertheless as far as I can tell users haven't been keen on adopting
this so far. Show the preference on the setup screen since many users
don't animate and will may want to quickly search or switch tools.

transform_snap_object: Fix snap in edit mode.

Do not use the texture space of a mesh to pretest the snap.
(The texture space is only really updated when you exit edit mode).
