Cleanup: remove 'orig' from ObTfmBack

This is runtime data and is re-evaluated before use.

DNA: rename Object.size -> scale

Resolves a common cause of confusion.

UI: motion paths panel layout tweak

- User better alignment for the paths_range_update button.
- Use Flow layout for the Display sub-panel items.

UI: armature properties layout tweaks

- Rename 'Draw Mode' to 'Display As', consistent with other properties.
- Use flow layout.

RNA: use distance units

UI: bake panel layout improvements

All the controls were just really thrown in there without any proper
organization.
This gives it more structure.

- Correct use of sub-panels to communicate hierarchy and sections.
- Use flow layout for toggles.
- Use consistent names for "Bake Type".

UI: improve light probe properties layout

Smaller adjustments to the Light Probe properties layout.

- Correctly use alignment for multi-property values.
- Correctly use sub-panels.
- Correctly use PROP_FACTOR for visibility_bleed_bias and
visibility_blur.

Fix T61187: Fluid Particle settings UI elements

Some properties were accidentally hidden for particle fluids.

- Made sure we show the Forces and Integration
sub-panels for particle fluids.
- Slightly re-ordered the sub-panels here, so that the same sub-panels
are at the top for Newtonian and Fluid particles.
- Separated the Fluid Interaction sub-panel so we can give it a unique
name.
- Removed lingering unnecessary 'Keys' label in the Keyed physics.

Cleanup: spelling

doxygen: update doxygen & add balembic group

DNA: rename Collection.dupli_ofs -> instance_collection

DNA: support renaming structs that use the old renaming hack

RNA: use clog for logging error messages

Some RNA errors are quite similar, use clog for consistent logging that
always includes the file, function and line number - making errors
quicker to troubleshoot.

Cleanup: style

Correct own mistake in near/far cleanup

Error in 2f737c4f475a5

doxygen: add newline after file

While file doesn't need an argument, it can't have another doxy
command after it.

Cleanup: conform headers to have license first

Also remove doxy comments for licenses and add missing GPL header.

DNA: comment on how to avoid DNA rename errors

Units: allow short unit names be case sensitive when needed.

To distinguish mW and MW without having to deviate from the standard
SI unit abbreviation. For all other units there are no changes.

Units: add support for light power units in Watt. Use for Eevee lights.

This affects point, spot and area lights. Sun light strength remains without
a unit. This change does not affect .blend file compatibility in any way, as
with the rest of the unit system it's purely a display and editing feature.

Not used for Cycles yet, that will be done after unifying the settings with
Eevee.
