More admin command RCON support

Add RCON support for the remaining admin commands to help give server owners more customization. /setwound, /setpermawound, /rewardgrowth, and /rewardwellrested are a few commands that are not currently supported off the top of my head but would be very useful to have.

Having access to these commands would be great for custom bots to help enhance the players experience and make each server unique.
