+  Changes:
+    - Mirroring blueprints will now mirror fluid recipes if GDIW (Gah! DarnItWater!) is installed.
+      This means mirroring a refinery blueprint will not break fluid inputs if using that mod.
+      This can be disabled on a per-player basis in mod settings.

+BlueprintExtensions_support-gdiw='Gah! DarnItWater!' is a mod that adds mirrored versions of recipes with fluid inputs/outputs.  If this is enabled and GDIW is present, recipes in blueprints will be mirrored when the blueprint itself is mirrored.
