V-Gears

As of fee1cd1, the installer extracts battle models, textures and (partially) animations. For animations, only the first frame is right

As of 4b4af67f, battle animations are extracted with all their frames. Some animations are still wrong, though.

Also, XML files relating party characters and scenes with their 3D models are generated during the installation, and V-Gears uses them to select the proper models.

It's now needed to create a map for commom character animation indexes (standing, weakened, dead, fleeing...)
