Upgrading RPG loot items modifies their name accordingly (#26144)

* Upgrading RPG loot items modifies their name accordingly

- the greater crowbar of many tales +2
- use item fortification scroll
- the greater crowbar of many tales +3

- Once the RPG loot event fires, a global is set which means all new
items will have rpg_loot datums attached to them.

Otherwise, everything functions the same. Item fortification scrolls are
only spawned when the event fires.

Using an admin spawned item fortification scroll on a non-rpg looted
item works, it'll grant that item only a RPG datum.

Made a /unlimited upgrade scroll if admins feel like buffing an item.

* Scroll

* Scroll, <i> nix

* Fixes vaporising items, negative quality

* Fixes runtime when upgrading non-rpg item

* Static lists

* Muh spelling
