Show All Pages Option (#177)

* show all pages:
- add option to 'show all pages' if additional non-seed pages are present in the wacz file
- only show checkbox if there are additional pages
- tweak page results to just show 'Pages' or 'Pages Shown' to avoid confusion over 'Pages Found'
- bump to 1.8.0

fixes #176
