Fix #24834: curves extrude + bevel gave bad normals on rendering.

This happened when removing vertex normal flipping in the render engine. But
actually the normal of the first face in the curve was flipped on rendering,
because it used a different vertex order than other places. Also removed the
hack that computes a face normal only from a triangle instead of a quad.

Small feature fix: zero-user blocks get indicated with "0" again in
browsing.

Bugfix #24860

On entering editmode Curve/Nurbs, the undo buffer was not
correct; storing old Curve/Nurbs object name. This caused
for example the Operator tool redo options to fail; it added
another curve on first use (with user pref "enter editmode).

Solved with adding good undo push + nicer code for curve and
nurbs naming.

use unit system for the grid floor (was only ortho before).

minor edits to exception formatting (remove ... or n from suffix)

bugfix [#24871] Unwrapping with Smart Project give a bad result.

fix for typo in mathutils vec.to_track_quat() argument parsing.

Changed some ui names for smoke parameters to make things less ambiguous.

Fix for [#19706] Smoke 'sticks' to Collision objects initial position
* Smoke got emitted inside collision cells, so it got stuck there.

changes in own recent commit broke MSVC building.

Changes to the ortho grid drawing based on discussion with Ton.
- ortho grid now draws scaled by the view3d 'Scale' setting, venomgfx noticed this was missing.
- so as not to confuse add scale next to unit display text, so rather then "Metres" it shows "Metres x 1.5" otherwise its confusing that grid lines are not in exact units.
- changed grid spacing to grid scale (needed for more logical behavior with units)
- when units are enabled grey out subdivisions.

Cached smoke wasn't being drawn on file load before going to simulation start frame.

transform snapping to a unit scaled grid was broken.

fix [#24870] ObjectActuator.offset_rotation in radians

partial fix for [#23532]
- Python calling operators didn't run WM_operator_properties_sanitize() so enum functions called from python were given a NULL context.
- PROP_ENUM_NO_CONTEXT and PROP_NEVER_NULL used the same value in the enum (possible conflict).

Particle fluid and boid settings didn't have a valid rna path, so they couldn't be animated.

use zero initializers instead of memset(), also change PointerRNA_NULL from an extern into a define.

Partial fix for #24773: Material Nodes - there isn't able to set keys on Mapping coordinates

Playback now works. The problem was that material/texture nodetrees were getting ignored completely, as I was assuming that all of these existed in the main->nodetree collection when in fact only the "group" nodetrees lived there. I don't really agree with this, but that's the way it is...
