+Akkadius: [Performance] Reworked how all log calls are made in the source
+	- Before we used Log.Out, we will now use a macro Log(
+		- Before: Log.Out(Logs::General, Logs::Status, "Importing Spells...");
+		- After: Log(Logs::General, Logs::Status, "Importing Spells...");
+	- The difference is 
+		1) It's 200-300x faster especially when log statements are inside very hot code paths. We already
+			had most hot paths checked before we logged them, but this blankets all existing logging calls now and not just the 
+			select few we had picked out in the source.
+		2) Strings don't get copied to the stack, popped and pushed constantly even when we hit a log statement that 
+			actually isn't going to log anything.
+				- We do an 'if (LogSys.log_settings[log_category].is_category_enabled == 1)' before we call a log function
+					in the log macro so the log function doesn't get called at all if we're not logging the category
+	- This has increased binary executables roughly 15KB
+	- The old extern for EQEmuLogSys is now named LogSys appropriately instead of Log (Ex: LogSys.StartFileLogs())
+	- The result keeps logging footprint non-existent for when we're not logging that category
+

 Akkadius: [Performance] Fixed an overhead issue where many hot paths would trigger quest subroutines and beneath that the code would
 	try to see if a quest existed perpetually (checking if file exists) even though it should have determined the quest
