Workbench: Add option to have world space lighting in studio light mode

This option is per viewport.

Having view space shading make sense when working on isolated objects like
if you were holding them in your hands. But for entire scene work, it is
better to have the lighting fixed to have a better spatial representation.

Workbench: Add back studio lighting presets

This changes a bit how the userprefs solid lights works. They are not
visible until enabling the "Edit Solid Light" checkbox. Once enabled the
current studiolight used for solid mode will be overwritten.

Once the lighting settings are tweaked, the user can click the
"Save as Studio light" button to save the current settings.
This makes it easy to create new lighting without messing the other
presets.

The studio lights are stored as ASCII files on the disk using a dead
simple custom format.

The UI/UX is not perfect and will be improved in other commits.

Also includes:
* Separate LookDev HDRI selection from Solid Lights
* Hide LookDev HDRIs from the Solid Lights selection list

Workbench: Rename orientation to type and Camera studio light to Studio

Templates: tweak sculpt to work w/o opensubdiv

added duplis as fracture "source"

this basically converts e.g. particle duplis to individual rigidbodies

Texture Paint: fix artifacts when using masks with symmetry.

For most brushes, texture painting uses a special mask accumulation
table in order to ensure that the amount of added color only increases
when the same pixel is touched multiple times by the stroke.

Unfortunately, only the mask texture was added to the mask before
this check, while normal, stencil, texture alpha masks were applied
after this check. This means that the check can pass if e.g. the
pressure is increased, but the final mask value is actually lower.
One might think that the mask values are fixed per pixel, but with
symmetry that isn't true. The result is a nasty stripe artifact due
to the discrete cutoff nature of the accumulation test.

In order to fix this, apply all masks before accumulation.

Bump version to 2.80 beta.

New splash image for Beta.

This one focuses on the development fund campaign. We plan to do more
more splash updates during the Beta.

Merge branch 'master' into blender2.8

GP: Add option to draw primatives from center

This allows primatives to be drawn from the center using the ALT key.
Also fixes SHIFT constraint not working correctly in all directions.
Both options can be used together.

Fix internal compiler error when building with VS 2017 (15.9.3).

It doesn't like alignment for function arguments, and I don't think this
alignment is needed.

Solution found by Ray Molenkamp.

Fix T57796: bad 'draw emitter' conversion, importing shared particle systems from 2.79b to 2.80

Not sure what those #ifdef's were supposed to do exactly... But one
thing is for sure, clearing that flag in particlesettings after first
encounter would prevent transferring it properly to other objects that
would use same particlesettings.

Cleanup: mark `PART_DRAW_EMITTER` of ParticleSetting drawflags as dreprecated.

Fix depth offset in paint mode wireframe.

The original offset was wrong because it applied a constant to
homogenous coordinates (the actual depth is z/w), which broke
totally if near clip distance was reduced.

A correct depth offset has to take slope into account like
glPolygonOffset in order to avoid dotted lines caused by
interpolation precision variations. When drawing wire lines
however only the slope of the line itself is accessible, so
also generally increase the offset when the object is close.

Fix T57878: 2.8 Opening project in Blender Crashes.

Crash was due to some modifier trying to access the editmesh of its
target just after loading, when that editmesh has not yet been
re-created...
