Increased exporting performance for packing wireframe stage.
Wireframe Snap parameter for Rigid part helpers exposes spline wireframe knot to vertex snap strength.
Bugfixes
Null VMeshRef pointers no longer crash when imported (mesh reference points to null mesh ID).
Wireframe spline knots missing matching vertices will not cause exporting error but instead issue warning message in MAXLancer log.
3db part name is now "0x0" instead of empty string, while the latter is legit object name in 3ds max it is rather inconvenient. This affect sub-object names too. Both old and new name work the same.
Hardpoint hulls for .3db have correct names when imported (previously they would have null part name instead).
VMeshRef default radius set to 0.0 instead of 1.0 (previously this caused problems for icon/ui models).
Texture library routines no longer write "Texture count" entry as it causes warning in game log.
