This mod makes all Inserters that don't already have filters have filters and modifies existing filter inserters.

Here is the list of changes:

1. All inserters that already have filters before this mod makes any changes will have their recipes disabled.
2. Technology effects that unlock those recipes are removed from their respective technologies. If that was the only effect the technology itself had, it is removed, and the tech tree is patched together from the two ends of that tech.
3. By default, when an inserter is placed, it's filter mode is set to Blacklist, which when it has no filters makes it operate like a normal Inserter.
4. If an inserter placed as a ghost already has filters, or existing inserters that already have filters set for them in your save file, then its filter mode will not be changed. However, if the inserter has no filters, then it will be changed to Blacklist. This includes if a mod has given filters to an inserter that doesn't already have them.
5. All existing filter inserters that have already been placed down on surfaces in a save are unaffected, they are not removed or replaced. The entities and recipes themselves also still exist, meaning they could (probably) still be accessed through something like Creative Mod.
6. For Modders: You can add a "ignore_filter = true" key to your recipe and technology tables before the data-final-fixes stage and it will make this mod ignore those recipes and technologies.

These changes are meant to closely emulate the filter inserter changes from FFF#393. I haven't done a lot of playtesting with other mods yet, pretty much only AAI Industry, so please report bugs if you found any. :D
