arogue5: fix player's typed responses getting put at the wrong place. Some sections of code that prompt the user for a string of input were calling get_str() with cw (the player-visible screen containing the map), which caused whatever the player typed to get printed starting at cw's idea of the cursor position, which was usually the Rogue's @-sign. This corrupted the map. The problem has been fixed by passing msgw (the message line at the top of the screen) to get_str(), so the player's typing appears where msgw thinks the cursor should be, which is in the sensible place right after the prompt. Some other get_str() invocations which used hw or stdscr have been left unmodified.
