Overhauled the config system, now supports block tags, properly saves on load, and is serialized using JSON format instead of JSON5.

New #inventorytabs:block_entities_without_inventories tag, for better mod compatibility

Fixed soft keybind conflict with multiplayer list, so the tab keybind does not consume the tab click event outside of the inventory (thanks Devan-Kerman!)

Excluded bed and redstone comparator block entities from showing up in the tab list
