Subject: [PATCH] Icewalkers and ghosts can now tell who joined and who left
 the Icemoon Dweller hole (#1062)

* Lets icewalkers and ghosts tell who joined and who left their hole spawner in the round via examining it twice

* Fixes a missing argument in examine()

* Apply suggestions from code review

Co-authored-by: Bloop <13398309+vinylspiders@users.noreply.github.com>

* Update modular_nova/modules/primitive_catgirls/code/spawner.dm

* Fixes the leave and log cache print logic
