Modify database lookup to allow for lookup of the nth entry for a

given keyword. Used for more varied recite speech, so that the same
prechosen synonym can be used for all of start/continue/stop/finish
reciting. The number of the entry is calculated in an embarassingly
hacky way: 
  (recite power + hp at beginning of recite + x_pos + y_pos)
   modulo total weight of the keyword. 

This makes sure that different synonyms get used, though always the 
same one (plus its shorter variant) during one round of recite, but 
it's not as random as I'd like. It works well enough for now, though,
and adds some much needed flavour to Zin.
