I'm not sure if this was a mistaken edit that the author made on check-
in or if we have a broken script that's generating these. For now I've
manually fixed it.
Fixes https://github.com/dcs-liberation/dcs_liberation/issues/1574
(cherry picked from commit 70dbe7c9ca7db73017608bde8eedaf2b3648fb82)
Adds a simple injector that iterates over attrs of an input class and
injects things that look like custom weapons into pydcs's weapons
classes.
Also updated all current mod aircraft configs to perform the injection.
