unify variables and deferred words

i really need local executable words instead of just variables.. how
to do so? context switching might just exchange the first body

it's fixed now as:

  : local-variable  dup @> 2 list
  	      dynamic-parameters push ;

  : local-xt    xt>body local-variable ;;

which works ok.. i changed some C code to make it more robust. don't
use it for non-deferred words.. maybe i need to simplify deferred
words a bit, unify them with "closures" and add an extra slot to

hmm.. deep change. not for now.
