- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.
This time roll back to originally discussed in the code review page approach
with simply bumping UI range for the property.
It's still not totally free from forward compatibility breaking (which is
already broken comparing to previous release) but at least it'll keep files
working inbetween of git blender versions in cases random factor was not
set above 2.0.

This is BAD code, but the particle kinking does not make it easy to
write a non-local modifier that requires neighboring positions,
curvature, etc. The feature is needed for Gooseberry.
This adds another level of clumping on child hairs. When enabled, child
hairs chose a secondary clumping target using a Voronoi pattern. This
adds visual detail on a smaller scale, which is useful particularly when
the number of parents is relatively small.
Natural fibres behave in a similar way when they become sticky and
intertwined. Hairs close to each other form a first twisted strand, then
combine into larger strands. Similar features can be found in ropes:

This is an alternative method to the current fixed function with a
clump factor and "shape" parameter. This function is quite limited and
does not give the desired result in many cases (e.g. long, parallel
rasta strands are problematic). So rather than trying to add more
parameters there is now a fully user-defined optional curve for setting
the tapering shape.
A stupid hack is needed here, changing the way the factor is applied to
angular bending springs. In cloth sim the bending factor of individual
springs is applied as a mix value between the bending stiffness and a
max value, but this max value isn't even used in hair sim so that
approach becomes useless.

This helps to create some variation in a hair system, which can
otherwise become very uniform and boring. It's yet another confusing
setting in a system that should have been nodified, but only option for
now (broken windows ...)

Without this the particle system only shows the actual non-simulated
hairs ("guide hairs") during edit mode. These hairs are used for goals
as well, so showing them in the regular viewport is pretty important.
Also the usual hair curves are interpolated along the entire length,
which makes it very difficult to see exact vertex positions, unless
using exact powers of 2 for the segment number and match the display
steps.

This is still using the old BVH tree collision methods to generate
contact points, similar to what cloth does. This should be replaced
by a Bullet collision check, but generating contacts in this way is
easier for now, and lets us test responses and stability (although in
more complex collision cases the BVH method fails utterly, beside being
terribly inefficient with many colliders).
amount and crashes after Cycles render.
This is a hack to fix this, but at this point the system is hopelessly
broken anyway and no good fix other than total rewriting is possible.
There were several small issues/inconsistencies if how particles' org face index was checked,
leading in some cases to invalid indices and hence mem access, in RNA UV/VCol compute for particles.
Note org code RNA one was copied from (in BI's convertblender.s) is much more complicated,
and seems to never reach those breaking conditions.
Also deduplicated most code in those UV/VCol particles funcs, they were doing mostly the same thing!
Finally, also got rid of annoying `NO CD_ORIGSPACE, error out of range` error message in console,
was another case of not checking whether we did have any faces in final mesh!
Crashes due to bad dm face calculation in particle RNA/cycles hair.
This stuff is a total mess, but this kind of check is used in other
places and prevents crashing at least.
Also fix material slot index not being properly initialized to 1, this got clamped
from zero only on drawing the UI.

The Emission panel now has a Use Modifier Stack option to emit particles from
the mesh with modifiers applied. Previously particles would only be emitted from
faces that exist in the original mesh. There are some caveats however:
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.68/Tools#Particles
* Editing number of segments for particle hair did not update the viewport.
* Hidden particles were confusing, the paths were drawn but without the points.
Now it draws the path faded to indicate that they are hidden/locked.
* Select tips/roots operators now have options to select/deselect/toggle/invert.
