## About The Pull Request
bzzt. kss bzzt kzz (fixes the static anomaly, it no longer does a weird
runtime related to attempting to run mob code on a spawner effect. The
resulting fucked up chat message is also fixed.)

bzzzap kzzazz mmm bzzzaap (Adds a weakref on mob spawners pointing to
their spawned mob. This is also a surprise tool that'll help us later w.
stuff related to manipulating entities after they've been spawned. I'll
prolly port the full mob spawner rework at some point)

bzzz
<!-- Please add a short description of why you think these changes would
benefit the game. If you can't justify it in words, it might not be
worth adding. -->

## Changelog

:cl:
fix: planetary static anomalies no longer drop a broken spawner.
code: mob spawners now store a weakref on their spawned object
/:cl:

<!-- Both :cl:'s are required for the changelog to work! You can put
your name to the right of the first :cl: if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
