v0.2.3 - The map's completion display follows the multiworld

Matched pair: install the plugin zip AND regenerate with this cw4.apworld. The plugin and the apworld share a version number and must match.

Requires Archipelago 0.6.7 or newer.

Seeds do not change: the same seed number generates the same layout as in v0.2.1 and v0.2.2, checked on 100 seeds across default, SPAN, casual and easy logic. Existing yamls keep working.

• The mission map's completion display follows the multiworld for every
  objective. Nullify, Totems and Collect were answered from your local save
  instead, so a mission your save had finished showed those objectives as done
  even where the multiworld still had checks open. Reclaim and Custom were
  already right. An objective now reads done only when every one of its checks
  is.

• The Units and Economy item groups no longer list Greenar Refinery.
  It is never generated (Factory unlocks the refinery), so naming it in a group
  did nothing. Placements are unchanged.

• The setup guides name the right save-archive folder. Switching slots
  moves your saves into archipelago/save-archive/<seed>-<slot>/, not
  <slot>/. The installation guide also lists all 21 options correctly and
  says how trap_percentage and the ERN maximums really count.
