Version 2.6.2 - OCR results are now saved in HTML HOCR format and PDF created by the program works better with Adobe Reader

Previous versions of Fopydo saved OCR results in RTF format. The OCR output is now changed to HTML HOCR for two reasons: better support for utf-8 in HTML and the fact that HOCR saves information about position of text blocks, lines and words.

I also modified the scaling of images in PDF output to facilitate annotating documents using Acrobat Reader (latest versions of Acrobat Reader for Windows and Mac made it easy to annotate and sign documents).
