Update Miku's Face Geomtry

I'm using MegaMan's face to make sure expressions work. Now that I've confirmed expressions work, the next step is to update the face to use the geometry provided by Xinus.

For the face, looks like we might be blocked on updating it as the game expects a specific number of triangles and uv's.

For the other textures, i should probably heal main and merge those in.
