Lucina 2.0 model update

- Features a near complete image overhaul with numerous alternations to visual assets and poses. Furthermore, a new (but currently unimplemented) pose called "Sword" has been created for situations where Lucina thinks words may not be enough. Expect to see it start showing up in the near future.
- Currently features no image editing (her eye, her boots etc...) The goal is to get community feedback on poses before image editing begins. If the consensus is that there are no major issues with the poses, image editing will begin in earnest.
- No notable dialogue alterations of note
