Always name the imported action slot "Slot" when importing BVH and FBX
files, for ease of switching between imported Actions.
Note: this is only adjusting the old Python-based FBX importer.
Previously the slot would be named after the file itself (BVH) or had a
combination of the animated object, the animation "stack", and the
animation "layer" (FBX). This meant that every imported animation would
get another slot name, making Action switching tedious.

The author field is displayed in the UI as "Maintainer",
most of the original authors are no longer active or are part of the foundation.
Since the core add-ons are maintained the same as the rest of Blender they should be shown accordingly.
The exceptions here are the GLTF and Hydra add-ons; these Khronos Group and AMD are included as maintainers.
The orginal author field is preserved in the chance the add-on looses it's "core" status.

When importing a BVH file with a parent node that has more than one
child that have offsets within `0.001 * global_scale` of the parent
node, the length of the parent node is considered to be zero.
For example: A parent node with `OFFSET 0 -0.1077 0`, two children with
`OFFSET 0 -0.1074 0`, and a global scale of `1.0`, the parent node's
length would be considered zero, therefore adding `global_scale / 10`
(`0.1` in this case) to the y component of the offset. The resulting
tail offset would then be `OFFSET 0 -0.0077 0`.
