Subject: [PATCH] Fix crash on exit if any modern particle callback is
 registered

All these smart pointers have to be cleared before the Lua state is closed. Ordinarily, we'd have a smart pointer to the Lua state defined earlier in LSI than these smart pointers, which would take care of destruction in the correct order, but tfw technical debt.
