Forgot to update tesseract spoofers to account for change in tesseract
parameters. Also the change to outputting multiple files in the collate
steps affected how ruffus passes information into downstream consumers
of those files.
If tess4 renderer needed to skip OCR on a page it would end up
duplicating the page contents onto the new page, rather than creating
a blank OCR layer and placing it on the output page. This created
duplicated content in output files.
