#218 Not open epub TOC on windows platform

[Olexandr]

If in epub book «"full-patch" = ./» then on windows platform toc not opened. On linux all work fine.
Example book: https://github.com/downloads/GArik/progit/progit.ru.epub

Problem in this part of code:
crengine\src\epubfmt.cpp
866: if ( codeBase.length()>0 && codeBase.lastChar()!='/' )
877: codeBase.append(1, L'/');
