changed: now we do not use std::string and char* in the Winix API

everywhere we are using std::wstring and wchar_t*
         (std::string and char* is used only locally in some places
         especially when creating a path to OS file system etc.)
added:   to the special thread when winix closes:
         a write function for curl: FetchPageOnExitCurlCallback()
         without this function the curl library will print
         the page's content to the standart output
changed: TextStream<> class from core can make
         UTF8<->wide strings conversions
removed: from config: utf8 option
         now winix expects UTF8 from the user's input (html forms, url-es)
         and outputs strings in the UTF8 format
