Add support for GNU Parallel about pmocr HOT 6 CLOSED

I already have a parallel job control function which is portable to bsd and mac.
It should be easy to send OCR function to background without using gnu parallel.

What's the purpose here ?
Is the purpose is to use tesseract on all cores (abbyyocr11 is already threaded) ?
Is the purpose to run on multiple computers ?

Yes, Tesseract does not support all cores by default, but your point that it running on multiple computers sounds very useful too!

It's called "poor man" ocr service, running on multiple cores should be enough :)

I've commited some quick and dirty parallel execution work.
Number of processes is set in config header.

Please test it and tell me if it works for you.

Just gave it a try and seems to work just fine..! I set the process limit to 3 on a system with 4 cores, I'll monitor if it uses more than 3 but so far it looks stable.

Commited what should become v1.5.
Fixes an issue introduced with parallel processing on filenames with spaces and adds a couple of options for tesseract. Feel free to update and test.
Also, feel free to tell me if you have other ideas for this script :)

from pmocr.

tested v1.5 and runs well. Also integrated instructions to run a new instance as outlined in Issue-7, it all seems stable!
