Try to copy the animated kart mesh.
Merge branch 'master' into copy_kart_mesh
Changed line endings.
Moved cloning of animated mesh into CSkinnedMesh (to get access to
private members). Fixed animation bug, caused by copying already
animated vertex position from LocalBuffer to Weight (so they were
then later animated again). Might need a better solution to avoid
copying mesh twice (LocalBuffer = Weight, followed by Weight = LocalBuffer).
Minor performance optimisations.
Fixed line endings.
Fixed ref-counting.
