1. use WM_COPYDATA to notify from yamy{32,64}.dll to yamy instead of mailslot if process can't open mailslot(typically in low integrity level as protected mode IE), this fix tickets #17769 and #18662
2. yamy{32,64}.dll put log to file in %USEPROFILE%\AppData\LocalLow folder for process in low integrity level as protected mode IE. to enable this, define HOOK_LOG_TO_FILE in hook.{h,cpp}
