Adds support for exporting animations for foreground models. It's not perfect and doesn't handle the Jak 2/3 animations very well in some cases (scale can often get messed up, especially for the LZO compressed ones, I have no idea what is going on with the data in those art groups sometimes, so that'll have to be revisited later...), but it does a decent job on Jak 1. Additionally, the `build-actor` tool has also been changed to support setting the `master-art-group-name` and `master-art-group-index` fields to allow for custom art groups to link their animations to a different master art group, which lets you add custom animations to vanilla art groups.
