Quad Amputee Stumpless

Makes stumpless quads nuff said.

v3 Realistic and Drawn changes

Fix for scars and weird holes on the stumps. Drawn is trained on anime/drawing style model and Realistic on a realistic model. Training data is the same however.

Proportions can be different in older tests, but I'm mostly noticing more detail in the realistic version.

Both should work fine for non realistic models, however from testing I like anime/drawn images on the realistic version more.

v2 changes

This version fixes the nipple issues and has better support for realistic models.

v1

Might be some issues with stump caps and nipples.
