* Moved the BASIC stub that calls the compiled program into it's own segment

named EXEHDR.
* Renamed BASICHDR to EXEHDR for the PET-II machines.
* Moved the call to CHRCH in front of the code that saves the zero page, since
  open files are sometimes remembered in the zero page, so we need to close
  them before we grab a copy.
