* MSG_002 doesn't display in RTL * Update Policy dialog loses RTL setting after the first paragraph * Some text displayed in native Windows message boxes is not using RTL (even as the Message Box itself will display the rest of the UI elements as RTL) * Detect if the relevant language pack is installed and use MessageBoxEx to display native message box buttons using the selected language. * All theses issues are part of #621 * Also remove trailing whitespaces
