Support for DCS 2.8.5.40170, including laser hellfire, pylon 5 for the
apache, and a more tolerant livery scanner (not all liveries will be
discovered, but Liberation at least won't crash).
Fixes https://github.com/dcs-liberation/dcs_liberation/issues/2880.
Includes the rewritten livery scanning code. It might need some more
tweaks to be fast enough, but it at least now doesn't spam the log for
machines that don't have DCS (or Liberation) installed, and it's not
slow until something tries to use it, so until we add the UI we won't
have to pay for it during startup.
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.
