docx driver doesn't handle different languages
I discovered this feature missing trying to convert my ebook to MOBI from DOCX. The book is in English, but I also have many phrases in latin and greek and I have set the Word spellcheck language to the appropriate one. The debug DOCX output has no lang attributes other than the document one.
The DOCX input driver should detect spellchecker language settings and set the appropriate lang attributes for the p and span elements accordingly.
I am using Calibre 64bit 2.10.0 on Windows 8 SP1.
I have attached a test Word document.
