Transferring investiture allows for filling unkeyed metalminds

[Xenon372]

Mantle version: 1.11.104
Metalborn version: 1.0.3
Forge version: 47.4.21

Steps to recreate:

1. Have an unkeyed metalmind with at least a little bit of investiture and another empty one (both must match your current ferring type)
2. Start storing in the empty metalmind
3. Transfer investiture from the unkeyed metalmind to the other one via right click
4. You are now filling an unkeyed metalmind

Transferring investiture in this way also allows for removing the identity from multiple stacked metalminds (rings, for example) at once.
