feat(preferences): apply "Large map" preference (extra window) [#198]

The `map` user preference ("Show the large map in an extra window") was
saved to users.map but never applied in-game. When enabled, the large-map
button on the map now opens karte2.php in a separate browser window
instead of the in-page iframe overlay (default behaviour kept when the
preference is off).

Also drop the "(not coded yet)" marker from the Large map section of the
preferences page and wire its title to the existing LARGE_MAP constant.
