Feature: Looping garage animations for legendary camouflages

Legendary camo add-ons now loop their garage animation in the Tankopedia viewer. It's always on, with no settings.

- The garage replay now also works out which motions end up looping, and the export writes only those clips
- Customization parts export skeletons, skin weights and sockets
- Parts render as primitives so their bones can animate, with attachments layered on top
- Base tank models are unchanged
