Store a map, minus all the players
Load a map in preference to reading from ascii
save the map on shutdown
Store regular and scheduled events in the map itself.  Pull them out and schedule them after loading.
Add some commands to modify the map, see how it works out.
--------------------------------
copy client.pl to admin.pl
abstract out common code
choose some reasonable commands
    toggle between wall and open tile
    create items
    destroy items
    move items
Refactor the status panel in UI to accept a closure
Look for other refactors in UI
Implement admin connections in server.pl
implement the map-editing commands chose earlier in the server
heavily refactor the server to move code into separate libraries
