Fixes alternate organ removal method

- De-braining and de-eying a detached head now sets the organ's vars
correctly.
- Slime people's (and golem's) slime cores are no longer robotic, this
will keep them from getting EMPed.
- As a side effect, this also fixes not being able to transplant slime
people brains.
- Fixes unEquip dropping organs.
