Tesseract 4 support

[bwakkie]

Would it be much effort to add support for tesseract 4? (https://github.com/tesseract-ocr/tesseract)?

This shouldn't require rocket science to get working, but I definitly need to setup a test machine with Tesseract 4 first, because my work environnment (CentOS 7) ships with Tesseract 3.

Seems that tesseract 3 and 4 both use the same syntax.
I've fired up a test machine today, and could use tesseract 4 without further problems.
Renamed "tesseract3" to "tesseract" to remove ambiguous config name.

Would you like to have a test run with current git before I release a new version ?

[bwakkie]

Please release :) I will check back at a later date when I have to batch process my 1000+ pdfs

I'll release shortly.
In the meantime, you may already use git master for tesseract 4.X.

Released.
