Features like menucolors and so forth, are now done in the
core, and passed to the window interfaces via add_menu().
TTY_PERM_INVENT was disregarding the passed color value.
That can be turned off by the option !menucolors.
If a way to turn off menucolors in TTY_PERM_INVENT (or
perhaps in any perm_invent implementation), while keeping
it on for other menus, then a new option will be required.
