James R. Barlow e5e011021b Remove the OCRMYPDF_program environment variables 
Really, this was just replicating the functionality of the PATH
environment variable, and users probably do that anyway.

James R. Barlow 2c24f67deb Rename “tess4” renderer to “sandwich” and make it default in Tess 3.05.01 
Tesseract 3.05.01 backported the textonly_pdf=1 which allows the use
of this superior PDF renderer prior to 4.00 alpha. This means that
the tess4 name is no longer accurate, so call it a sandwich because of
its merge-preserve characteristic. Preserve the tess4 name. Fix the
documentation and tests to reflect this.

Make it the default, because it’s better. It does not have the issues
the “tesseract” renderer does prior to Tess 3.05.00 with rendering
PDFs that Ghostscript corrupts, and it produces better output without
re-rastering.

Deprecate some old stuff to avoid the test suite growing obscenely
large.

James R. Barlow 234183ecd2 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

James R. Barlow cb06359c0b Turn on Tesseract 4 cache in test suite 
Travis is too slow without it, and perhaps it’s overly paranoid to
never cache Tess4. Maybe nuke the cache occasionally to be safe…

James R. Barlow c8a4cbcf17 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.

James R. Barlow b9b12e2879 Ensure that ocrmypdf stops and reports an error if Ghostscript fails 
Past behavior was to continue and let ruffus puke eventually

James R. Barlow a4f07756a5 tesseract caching: don't transcode tesseract's output, hash source file 
For sanity's sake, deal with tesseract streams in binary without
transcoding (via universal_newlines, etc.). The only differences are
printing messages regarding spoofing.

Also hash the source file so that changes to the cache mechanism
invalidate old cache automatically. That is probably too aggressive,
but simple and safer than the previous approach.

This reduces total execution time to 164s on my machine, down from
about double that.
