fixed: when signal comes winix properly exits

fixed:   when winix exits the session data were not properly destroyed (memory leak)
         we should set request.session pointer to each session when deleting sessions
         from session_container
         the session data were not properly destroyed when winix checked for 
         outdated sessions (and when it was removing them)
fixed:   performance (memcpy used too often)
         in some places there were reserve method used (on std::wstring/std::string objects)
         especially in AssignString() method and TextStream<> object
         if we add a new string we should check the new size
         and only call reserve() if the new size will be greater than existing one
         (plus some constant)
changed: fcgi objects moved to App class (from Request)
         now we use thread safe methods (e.g. FCGX_Accept_r)
added:   log_plugin_call option to the config
         default: false
         when true winix log when a plugin function is called
added:   winix parameter 'nostat' for not calculating statistics
         (useful when making performance tests)
