remove debug.exit(); add debug.isnan()

Browse source 
- exit was only justified at times where fgcommand() needed an explicit
  node statement, which made using it a bit clumsy. Nowadays that's only
  fgcommand("exit"), which is as good as debug.exit() was.
- isnan() is really only for debugging and, thus, not in the global
  namespace. Nasal code should never generate NaNs (though it's easy:
  var nan = 1/0; There! :-), and NaNs imported from the C++ side (tied
  properties!) should get fixed there. IOW: routine checks for nan in
  Nasal can only be temporary hacks/debugging measures.
