Scenes NEXT variants

The sex doll NEXT variant, currently the only variant, is now updated to the latest NEXT version.
This means all new sex positions are available, adapted to fit the female to a sex doll role, and all other features present in the NEXT template it's made from.

There's also a image based UI to load a sex doll box. Before was text, now it's box cover images. Nothing fancy or new, just nice to see pictures instead

Have fun.

Upgraded to the NEXT template.
V2 uses the 2023 template.

Turns out the triggers to turn the box on and off were not well though about because loading the subscene would break them

The boxes subscene is now a child of a empty atom. The empty atom is always present in the scene, so enabling and disabling it will not break triggers and will act on the child subscene as intended.

Added as a dependency is my sex doll boxes VAR for easier loading in the scene.
