Clean up display_region_map()

Browse source 
Without ARG1, display_region_map() formats a rectangular area around
CURX,CURY, so it can use do_map().  Ugly, and duplicates some
unit_map() functionality.

Factor snxtsct_around() out of unit_map().  Inline do_map() into
display_region_map(), so we can use snxtsct_around().

Don't mess with player->condarg.  Leftover from when we abused map()
here.
