[Fix 1910212] Add M_SPEAKS to large numbers of monsters. This does not

          automatically increase message "spam" as long as no 
      messages are added in speak.txt. An exception are the reaper
      for whom I've added some fitting messages, and Xtahua who
      already has messages that just were never output.

The following monsters that couldn't speak before and now potentially can: all cen-/yaktaurs, all draconians, all elves, (hob)goblin, merfolk, all orcs, hungry/flayed ghost, minotaur, curse skull/toe, Angel/Daeva, giants/cyclops, efreeti, sphinx, all kobolds, (ancient) lich, greater mummy/mummy priest, all naga, all ogres, all trolls, all vampires, human, hell knight, necromancer, vault guard, reaper, Polyphemus/Tiamat (have no speech defined), and Xtahua.
