Merge decoding.  Closes #39 

Remove leading zeroes and add name prefix.

For a couple Oblivion NIFs which are pre-Havok version yet somehow use Havok..

Removed compounds:  bhkRDTConstraint, bhkRDTMalleableConstraint.

Renamed compound: SubConstraint->ConstraintData (to reflect hkpConstraintData*)

Created:  MalleableDescriptor (to reflect other Descriptor compounds)

Corrected bhkRagdollTemplate inheritance.  Fully decoded bhkRagdollTemplateData.

bhkRDT now load without error or link validation warnings.

This was necessary so that Fallout3HavokMaterial actually applied to all FO3 NIF versions (e.g. User Version 2 == 16)

Pull in some of the documentation from #39 and fix the type names and the bone transform layout.

Seems niflib wants that row to be a special type, so fix "InertiaMatrix" to be the real type, `hkMatrix3` and use it for the Inertia Tensor.

Changes to:
- BallAndSocketDescriptor
- Renamed PivotAB to ConstraintInfo
- bhkBallSocketConstraintChain
- bhkPoseArray

NiTimeController, BSBehaviorGraphExtraData update

Num UV Sets fix.  Merging as I have used this for months in NifSkope without issue.  Handling it as one ushort instead of two bytes is the only correct way due to endianness issues.  Addresses all regressions with Bethesda NIFs as well as maintaining non-Bethesda NIF support.  Closes #51 

This is a redo of #51 since I did not seem to have permission to rebase the PR.   These changes work for all games and fix all FO3 UV Sets regressions.

The only downside is for UV Sets > 1 in non-Bethesda games the UV Sets count now becomes a combination of flags.  UV_1 + UV_2 = 3 UV Sets,  and UV_1 + UV_4 = 5 UV Sets and so on.

This was the only way to treat the field as a single ushort which is necessary for endianness changes when reading the field 16 bytes at once because the value is read/written 16 bytes at once and uses bitmasking to retrieve the UV count.

The phrase "Shape Scale" was used as "Scale" was already taken for the
MOPP Scaling Factor and is referred to by code.

Did bhkRigidBody and added the correct rows to bhkWorldObject for
correct bhkSimpleShapePhantom size.

Motor types decoding from https://github.com/jonwd7/0x6e6966746f6f6c73/blob/0532cd7bdffc10b578c8b8e841a0f6206c62d6ab/nif/bhk.bt#L367

Added motor descriptor to Prismatic constraint.

Added motor variable explanations, added default values and removed the white spaces.

Added motor type selector for Ragdoll and Limited Hinge constraint.
