Several proxies

Set redis.activado: true and a different proxy-id on each proxy. Each one publishes its players to Redis every 2 seconds, with an expiry: if a proxy goes down, its players disappear by themselves in about 10 seconds. Messages, staff chat, friends, /send, /find and /glist work across proxies. With a single proxy you do not need Redis.

Each proxy takes one seat of the license.
