add option for original domain

add option for original domain

- this is part of the implementation of scoring mechanism for next/prev page
  links.
- scoring framework uses files, instead of live urls, when calling distiller.
  detection of next/prev page links expects the same domain for current page and
  paging links, which isn't the case when current page is a file://.
- this is rectified by having an option to specify the original domain
  associated with the current page if it's a file://.
- detection algorithm uses this original domain when determining location host.
- fixed and added tests.
