Merge branch 'cloneActor_fix' into 'master'

`self_resurrect` now properly not copied by clones.

Fixes a typo in `Actor.clone_nodes` that governs which fields are not copied by actor clones (Multiply, Inner Demons, etc.). `self_resurrect`, which is used by liches and some other enemies, had a typo (`self_ressurect`), preventing this behavior.

The bug was most notable on clones of The Master, who currently spams his death dialogue (`self_resurrect_chat`) when his clones die, leading to this:

This MR is save-safe, although already existing clones will have their illegal `self_resurrect` field.
