Remade the menu system slightly. All functions invoked from menus now use

the Menu typedef as return type, and *ALL* menus that intercept USB connect
can then return MENU_REFRESH_DIR so that the parent (any parent really) that
do file or dir-accesses knows that and can do the refresh. If no refresh
is needed by the parent, MENU_OK is returned.

Somewhat biggish commit this close to 1.3, but we need to sort out this
refresh-after-usb-connected business.
