Die of fate tweaks and fixes (#42073)

* Die of fate tweaks and fixes

🆑 coiax
fix: Rolling a 6 with a die of fate now reduces your speed as intended.
fix: Rolling an 8 with a die of fate will cause the explosion to be
around the roller, not the die.
tweak: Die of fate effects now make loud visible messages so it's
obvious what has happened.
admin: Dice can now be "totally rigged" with admin edits to
unconditionally always roll a certain value, rather than just some of
the time. A new "cursed die of fate" has been added to demonstrate this
effect.
/🆑

- new proc `do_smoke` that does basic smoke effects, to avoid the same
pattern for making smoke effects.
- Dice rigging has been split into two vars, "rigged" for the severity
of the rigging (not rigged, basically rigged, totally rigged), and
rigged_value for the value it's trying to rig to.
