xrCore: Debug: correct path to fsltx in error message

Слиты xottab-duty запросил слияние github/fork/vTurbine/debug/noltx_error_path в xd_dev

Created by: vTurbine

  • When no game data found but -fsltx option specified show the missing .ltx file path instead of last checked directory
  • Message box title changed to make the error easily distinguished from system/other app errors
