Quick bug fix, tried to fix broken save files where the . is replaced with ,
Also, fixed a keybind bug where it wouldn't let you change the keybind if any other keybind had some but not all the same keybinds.

I fixed undo/redo not working, now to figure out other things

Everything broke, who knows why

Fixed another duplication glitch, this one with saving. Also added changeable hotkeys.

Fixed duplication bug, fixed a scaling multi-select problem and fixed the preview image
