Prompt is not output after "reading .ini" file line (made usage display ugly).

Added [path/ini_file] to usage info.
lputs() no longer tries to print prompt if it is NULL.
Using fexistcase() for $HOSTNAME.ini (case insensitive).
ini file can now be specified on the command-line using forward-slash on Win32.
