This should fix most of the problems, aside from a few graphical icon issues - styles are fixed, checkboxes are moved to the new on_gui_checked_state_changed event, and so on. I can't say for sure that nothing is left unbroken, but the vast majority of the functionality should be working.

Did you manage to get the ingredient sorting to work properly? I don't know why it wasn't changing the filters when pressing the buttons for me.

The checkboxes relied on old behaviour, where they would trigger on_gui_click; in 0.16 they exclusively call on_gui_checked_state_changed instead. So yes, it should be working, unless I missed any checkboxes.
