When importing an animation from FBX or BVH the fcurves are currently shown as a very long list in the dope sheet.
When you manually create a keyframe they are grouped by bone name, which is much more user friendly. This patch groups imported animations by bone name too.
The changes are trivial:
- In the FBX case it was falsely using the object name to group all curves rather than the bone name.
- The BVH importer simply wasn't using the grouping feature at all.
