Fixed a couple errors people were experiencing.

Also added an experimental stacked input feature. To enable the feature, allowing your recipes to require a certain amount of item, add this to your config
It's disabled by default because I had to hack in this feature and I can't guarantee it will work perfectly.

There shouldn't be any kindof dupe issues or anything like that, it just doesn't always update the recipe properly when you insert items. For best results, place the whole stack at once instead of trying to right click items in one at a time. This is a bug due to Minecraft not understanding that item amount matters. I'm still thinking about a fix for that.

Let me know if you run into any problems and I will fix them tomorrow morning!
