Bug Fixes (#4714)

* Bug Fixes

Fixes #4616
- All ladders are now anchored and cannot be dragged, including dive
points.

Fixes #4663
- Trying to fill a full container from a toilet will inform you the
container is full, and thus fail.

Fixes #4705
- Being gibbed/dusted/melted will unbuckle the victim prior to their
gruesome fate, allowing their spirit freedom to no longer haunt the
buckles that bound their mortal form.

* Because apparently we shouldn't trust people to use "delete" properly
