possible fix script for bug for demanding tribute from guardian entities

[ab9rf]

Per Putnam, "latest beta has a known crash when demanding tribute from guardian entities (i.e. mythical sites)" and provides the following script

function get_first_civilized_its_probably_dwarf()
  for k,v in ipairs(df.global.world.raws.creatures.all) do
    if v.OCCURS_AS_ENTITY_RACE then return k end
  end
end

local r=get_first_civilized_its_probably_dwarf()

for k,v in ipairs(df.global.world.entities.all) do
  if v.race==-1 then v.race=r end
end

We may want to implement.
