/* One of the following two must be used.  SetTalesDir(string dir) will set a
   directory which will contain tale files.  Each tale file should consist of
   the following:
   action#delay      where action is what you want the NPC to say, and delay
   is how long before the next action.
Example:
say this is the first part of the tale#5
emote this is the second part of the tale which is really long so that it will span a line.  Note that there is no line feed in the middle of this line#4
speak last line#1
End Example.

If using SetTale(mapping tale) instead the mapping should be like the
following
SetTale( ([ 1 : ({"say this is the first part of the tale",5}),
2 : ({"emote this is.....",4}), 3 : ({"speak last line",1}) ]) );
