[WIP] Generic peep 3D model

[saadbruno]

This is a basic test on the generic peep model, based on the model initially made by Oli414

but I also redid most of the topology to have a better edge flow. Rig works well and it's possible to subdivide the surface if necessary (i don't think it is)

I've retroactively made an issue (#17) to further discuss the shape of the official peep model
