Problems with lambdas and references

OK, so I think I was working on the parameters for CreateRoom() in lua,
but then shit just got ot of control. IDK, I'm probably going about this
all wrong anyway. I just want to finish this stage, and reach the high
water mark again.

+## Outline
+
+Tortuga is a 2D multiplayer JRPG featuring permadeath, with an emphasis on multiplayer cooperation, exploration and customization. The game runs on customizable public and private servers.
+
+This game is inspired by classic 2D RPGs (Final Fantasy, The Legend of Zelda), as well as more modern sandboxes amd MMOs (Minecraft, EVE Online). This project is currently independently created and funded, with the goal of creating a game that will engage the players and inspire a large community.

+This is the README for Tortuga's demo build. The source code is available at:
+
+   https://github.com/Ratstail91/Tortuga
+
+The current build may have bugs, missing features, bugs masquerading as
+features, etc. You can report a bug/feature here:
+
+   https://github.com/Ratstail91/Tortuga/issues
+
+Please note that this game requires a functioning server to operate correctly.
+Both a game server and game client are included in this package.
+
+-------------------------
+Instructions For Setup
+-------------------------
+
+1. To create a server, simply run server.exe.
+2. To join that server, run client.exe with config settings not already in use.
+    (Note: This process will be streamlined later).
+3. To change the config settings, open rsc/config.cfg
+4. These settings must be unique for each player:
+
+* client.username
+* client.handle
+
+5. There are currently two options for 'client.avatar':
+
+* client.avatar = elliot2.bmp #male
+* client.avatar = coa2.bmp    #female
+
+6. When you've correctly set these values (good luck), select 'Start' from the
+    main menu; this displays the list of available servers.
+7. Select the name of your server (default is 'local') and select 'Join'.
+8. Welcome to Tortuga, enjoy your stay.
