Made CMatrix3D::Translate assume something sensible about the structure
of the matrix, so it doesn't have to do a matrix multiplication.
Added quaternion nlerp (but haven't used it anywhere).
Changed animation interpolation so it loops smoothly in the actor viewer
but (hopefully) doesn't interpolate dying units into a half-upright
pose.
This was SVN commit r4932.
Added UnitAnimation class, to act as the interface between the entity
and actor. (Currently doesn't work very well, but it does make
animations loop smoothly and sometimes kind of makes them stay
synchronised.)
Fixed corpse animation - it now plays the final frame of the death
animation before turning static.
Fixed update/interpolate timings.
Added JS function saveProfileData.
Updated ffmpeg library.
This was SVN commit r4880.
