	@short		implement command application to show login dialog and save his information in temp. file!
	@descr		We need this temp. file to share informations between our dialog and different processes, which
				can't use vcl directly. Caller of this executable give us the file name as an argument - we save
				all informations in it - caller can read it and MUST delete temp. file.
				This is neccessary for example; to hide the password!
