experimental config option TTY_PERM_INVENT

Add a rudimentary experimental always-up inventory display
capability to tty when the perm_invent option is in effect.
It requires an additional 28 rows available on the terminal
underneath the bottom status line.

It hasn't been optimized for performance as of yet.
