Original Racing Scores Functionality (#257)

This macro makes it use the stdcall calling convention when compiling
for 32-bit Windows. Its absence was technically a bug, but it's a no-op
on 64-bit Windows.

 ### Getting Started
 #### Method A: Installer (Easiest)

 2. After a few moments, the client should open: you will be given a choice between two public servers by default. Select the one you wish to play and click connect.
 3. To create an account, simply enter the details you wish to use at the login screen then click Log In. Do *not* click register, as this will just lead to a blank screen.
 4. Make a new character, and enjoy the game! Your progress will be saved automatically, and you can resume playing by entering the login details you used in step 3.

 The original game made use of the player's actual web browser to launch the game, but since then the NPAPI plugin interface the game relied on has been deprecated and is no longer available in most modern browsers.

 The goal of the project is to faithfully recreate the game as it was at the time of the targeted build.
-The server is not yet complete, however, and some functionality is still missing.
+While most features are implemented and the game is playable start to finish, there may be missing functionality or bugs present.
 
-Because the server is still in development, ordinary players are allowed access to a few admin commands:
+Depending on the server configuration, you'll have access to certain commands.
 
-![](res/sane_upsell.png)
+For the public servers: Original has item spawning, the ability to set player speed/jump height, and teleportation enabled (default account level 50).
+Meanwhile the Academy server is more meant for legitimate playthroughs (default account level 99).
 
-### Movement commands
-* A `/speed` of around 2400 or 3000 is nice.
-* A `/jump` of about 50 will send you soaring
-* [This map](res/dong_number_map.png) (credit to Danny O) is useful for `/warp` coordinates.
-* `/goto` is useful for more precise teleportation (ie. for getting into Infected Zones, etc.).
+When hosting a local server, you will have access to all commands by default (account level 1).
 
-### Item commands
-* `/itemN [type] [itemId] [amount]`
