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.

+
+## Code guidelines
+
+Alright, you're up to speed on Git and ready to go. Here are a few specific code guidelines to try and follow:
+
+### Match the styling
+
+Pretty straightforward, make sure your code looks similar to the code around it. Match whitespacing, bracket styling, variable naming conventions, etc.
+
+### Prefer short-circuiting
+
+To minimize branching complexity (as this makes the code hard to read), we prefer to keep the number of `if-else` statements as low as possible. One easy way to achieve this is by doing an early return after branching into an `if` block and then writing the code for the other path outside the block entirely. You can find examples of this in practically every source file. Note that in a few select situations, this might actually make your code less elegant, which is why this isn't a strict rule. Lean towards short-circuiting and use your better judgement.
+
+### Follow the include convention
+
+This one matters a lot as it can cause cyclic dependencies and other code-breaking issues.
+
+FOR HEADER FILES (.hpp):
+- everything you use IN THE HEADER must be EXPLICITLY INCLUDED with the exception of things that fall under Core.hpp
+- you may NOT include ANYTHING ELSE
+
+FOR SOURCE FILES (.cpp):
+- you can #include whatever you want as long as the partner header is included first
+- anything that gets included by another include is fair game
+- redundant includes are ok because they'll be harmless AS LONG AS our header files stay lean.
+
+The point of this is NOT to optimize the number of includes used all around or make things more efficient necessarily. it's to improve readability & coherence and make it easier to avoid cyclical issues.
+
+## When in doubt, ask
+
+If you still have questions that were not answered here, feel free to ping a dev in the Discord server or on GitHub.
