ePUB version plus 3 new languages

We've added Polish, Hungarian and Serbian translations of the book, and now each language is now also available as an ePUB. We'd like to thank our translators:

Smilja Ignjatović(Serbian)
Tymoteusz Masiakowski & Tomasz Stecko(Polish)
Attila Magyar(Hungarian)

We've had the Polish and Hungarian translations for a while, but we had some font issues and we have resolved those now. We had to re-format the entire project. You may notice some font changes between the old versions and the new ones for some of the other languages.

Cheers,
Rek & Dev
