Depsgraph: Keep track of original particle system

Allows to have quicker lookup in particle edit mode.

Particle edit: Add missing looking tag in cut brush

Particle edit: Allow children to be visible in edit mode

Follows tool settings, tested without copy-on-write.

Enabling copy-on-write still needs verification and likely some fixing.

Particle edit: Move cache update to particle batch cache implementation

The idea is to allow "regular" strands to update edit cache and hence
get the final update strands.

Draw manager: Pass object to hair batch cache

Currently unused, but is required for an upcoming work.

Particle edit: Make check to work within copy-on-write concept

Not fully optimal, we can probably store pointer to original psys
similar to ID's orig_id.

Particle edit: Edit path invalidate should trigger particle system path re-cache

Don't try to bend existing design, just follow it. It's not nice, but is
working. Just bring it back, then repeal and replace system as a whole,
making sure every bit is working according to a design.

Such quick patches only trying to make local sense of a system, defeating
it's design.

Particle edit: Restore weird-looking conditions in evaluation

They might be looking weird, but they match conditions when children particles
are to be re-calculated for particle edit.

Particle edit: Re-cache edit path if it's NULL

This is what old particle drawing code was doing.

Particle edit: Decouple caches for regular and edit strands

Makes it possible to have children strands to be visible during combing.
Actual implementation still needs work though.

Particle edit: Make visibility check to be per-particle system

This way we can see other particle systems while combing another one.

Particle edit: Use proper batch cache flag

Also tag batch for invalidation when using cut brush.

Particle edit: Tag for updates when changing tool settings related on edit mode

Particle edit: Fix missing hair edit after toggling edit mode

Fix hair edit mode after recent fix for DEG sued from draw code

Modifiers on Lattices now work

Tested with Hook and Armature modifiers. Requires CoW to be enabled.

Workbench: Renamed Overlap to Outline

Outline is reserved for the Overlap Overlay

Fix broken PoseMode editing when CoW is enabled.

We need to get data from evaluated object/posechannel too, then...

Fix T55078: Assert statement

Change startup defaults

- Default Lamp increased strength (10x stronger)
- 3D View & Camera Lens = 50mm
- Camera film size = 36x24mm Full Frame
- Render Size Percentage = 100%
- Render Display = New Window
- Scene Units = Metric
- Color Management View = Filmic
- Workbench Object Overlap = ON
- Headers on top for all editors, except the Timeline at the bottom
- Default Properties tab = Object Properties
- Generate UV's = ON
