arogue7: fix a display bug when viewing inventory after restoring. The restore() function displayed a status message via wprintw() instead of using the msg() functions. If the inventory was then viewed before a call to msg(), msgw would obscure the first lines of the inventory list. There are surely more bugs related to messages.
