Distinguish nominal and allocated size of hair volume attributes.

This allows keeping extra memory around for later use instead of freeing
every time the attribute needs to be resized (compare to std::vector).

Added a basic volume data structure for hair simulation.

Using volumetric description of certain hair simulation quantities
allows very efficient calculation of otherwise costly effects, such as
hair-hair collisions (at the price of reduced accuracy).

using inner material for finding inner vertex group now, other direct attempt was not successful

Merge branch 'master' into hair_system

Adding the official bullet documentation by erwin coumans for v2.82 (current one)

Merge remote-tracking branch 'origin/master' into soc-2014-bge

float breaking angle and automatic deactivation (manual re-activation) of auto-execute when sim is started

Take care of at least some of the crashes experienced during Gooseberry
meeting.

WIP inverse transform, still misbehaving

Merge branch 'hair_system_squash' into testbuild

Hair System test.

Missing scons include entry.

Revert "Hair System test."

This reverts commit 9fedf885b4e413865250b1673dd31d5ab3896584.

Merge branch 'hair_system_squash' into testbuild

Hair System test.

Fix for hair root transformation: was missing a world/object space
transformation.

Fix display issue

Reimport code from new solver to particles. Result is crappy
and positions are not updated very well, but it's a start.

Disabled hair debugging code, due to excessive memory consumption and
overhead.

This can be implemented much nicer using a hash table and statically
typed solver function templates, but for now just disabled it.
