A few, mostly untested, fixes to the SAGA script engine:

* The frame pointer is updated. This won't make any difference since we
  don't actually *use* the frame pointer yet.
* Return values from script functions are handled like in the original now,
  i.e. the function sets thread->retVal and lets the call instruction push
  it onto the stack. (There are two call instructions, one that handles
  return values and one that doesn't, so the script function doesn't know
  if it should push or not.)
* Script return values are handled.

None of this makes any noticeable difference to the ITE intro.
