Fix for particle system copy: This has to make sure the ORIGSPACE data
layer is available.

Otherwise particle mapping to the new mesh cannot work with subdivided
and constructively-modified meshes.

Added a "specials" menu button next to the particle systems list for
accessing the copy operator.

Changed the workflow for the particle system copy operator to the common
active-to-selected pattern.

New operator for copying (hair) particle systems from one object to
another, including edit data (grooming).

This uses basically the same method as the existing connect/disconnect
feature. The main difference is that it allows working with multiple
objects and transferring the //particle/hair data// instead of the
//mesh// data (which is what connect/disconnect expects). This is a much
more realistic workflow when rigging, topology etc. changes and
groomed hair has to be transferred to the changed model.

Removed unused particles pointer from particle edit data.

New texture influence option for particle kink amplitude (as opposed to
frequency).

Renaming "Kink" texture influence to "Kink Frequency" to be more
specific.

Spiral rotation axis was not always fully normalized, avoid an assert.

Make random child length work again with the spiral kink mode.

Add missing stub to the player, so buildbot keeps delivering gooseberry builds

Allow clumping and roughness in Spiral kink mode as well.

This requires interpolating the parent key properties, because no single
parent key can be mapped to each key on the children any more.

Optional randomization factors for the spiral radius and axis orientation.

Support in Cycles for the extra spiral keys in hair paths.

Nicer calculation of the kink axis and result of the spiraling for
negative radius.

Removed unused old code.

Disable the path length check for spiral kink mode.

This test is terribly expensive for some reason and not necessary for
for the spiral mode anyway.

Fix for calculation of the key velocity on the last child hair segment.

Another crappy approach to spirals on hairs, crazy expensive though.

Spiral kink mode for particles.

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.

Optional clumping noise feature for simulating twisted hair strands.

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:
