Additional Skyrim Havok materials
Added Skyrim specific values for "Layer" and "Col Filter" in bhkRigidBody. "ColFilter" renamed to "Flags & Part number".
Changed "Unknown Integer" after each of Skyrim Material in Chunk Materials array of bhkCompressedMeshShapeData to "Copy of Skyrim Layer". Because this value is 32bit long but Skyrim Layer is stored only in 1 byte, special enum called "SkyrimLayerCMSDM" created. It has identical contents as enum "SkyrimLayer" and only storage type is set to "uint".
UnknownInt2 of NiGeometryData is SkyrimMaterial

Tested with several Skyrim vanilla nifs containing effects and it looks ok. Also got load errors when using "!=0" syntax, so agree to use old syntax.

fix for HalfSpaceBV compound

Added one unknown float to the end of "HalfSpaceBV" compound as it seems that it has four unknown bytes after "Center". Problem reported at niftools forum http://niftools.sourceforge.net/forum/viewtopic.php?p=28704#p28704
Fixed error in Tangents and Bitangents lines.
