arogue7, xrogue: add support for keypad 5.

Keypad 5 is now equivalent to the '.' key.

XRogue does not include md_readchar() and its ability to work around
deficiencies in the terminfo entry. So the key will not be recognized
in screen/tmux or anywhere else without the kb2 capability.  Adding
md_readchar() would be more complex than it was for Super-Rogue, since
XRogue already does KEY_* interpretation in command().
