Fix issue in sandwich renderer when skipping OCR on a rotated and deskewed page
...
If OCR is skipped due to --tesseract-timeout or similar, and the skip page is rotated with /Rotate, and the skip page was deskewed or had other image processing, then the skip page was created with the wrong dimensions causing the output page to be cropped.

Fix: Tesseract 3.04 is sensitive to order of configuration commands
...
“txt hocr” is not acceptable and does not produce expected output .txt
while “hocr text” works fine, so switch the order everywhere.
Should fix #169

Fix test suite breakage after sidecar feature added
...
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.

Fix issues with —pdf-renderer tess4 page skipping
...
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.
