## About The Pull Request
Does a full shutdown of auxlua when the lua subsystem shuts down. This
should unpin the dll file.
Compare `AUXTOOLS_SHUTDOWN` code with `AUXTOOLS_FULL_SHUTDOWN`, let me
know if I'm mistaken:
### AUXTOOLS_SHUTDOWN
bc5b2cf019/auxtools/src/lib.rs (L346)
### AUXTOOLS_FULL_SHUTDOWN
bc5b2cf019/auxtools/src/lib.rs (L365)
## Why It's Good For The Game
Fixes auxlua keeping the dll pinned when the server is in a process of
shutting down.
