Next planned steps in plomrogue development:

IN GENERAL:

- expand use of hardcoded_strings module(s)

BOTH SERVER/CLIENT:

- make server and client communicate by specific world state info requests 
  in server/out, replacing server/worldstate

CLIENT:

- re-work unnecessary complex command / keybinding / server message mapping

- unify ping_pong_test() and try_growing_queue()

BUILD PROCESS:

- erlehmann's redo scripts are not OSX-compliant, see:
