- fixed light components throwing errors when receiving an invalid color value to the "set_color" input

- fixed it being possible to connect wires to more than two items by selecting another item while dragging the wire
- relay components break if too much power is directed through them
- relay components are active by default and the can be toggled on/off in the editor
- bool properties show as checkboxes in the editor
