process multiple html files with hocr2djvused

[jwilk]

Issue reported by @thkoch2001:

Hi,

I ran tesseract manually on multiple image files (try GNU Parallel!) and ended up with one html (hocr) file for every page. To combine those html pages to one djvused script I hacked your hocr2djvused a bit.

My version now optionally also accepts input file parameters and processes those as consecutive pages.

The patch doesn't look crazy, but at least documentation would have to be updated (lib/cli/hocr2djvused.py:31 and doc/hocr2djvused.xml.

Some nitpicking:

• I prefer lst += x to lst.extend(x).
• Please keep indentation consistent with the rest of code.

Implemented in f9922a6.

Fixed in 0.7.11.
