Implement a "Switch" parameter data type

[LagoLunatic]

Switch parameters are extremely common among actors but it's not immediately intuitive how they work. It might be helpful to split it from a single integer spinbox into a dropdown+spinbox combo widget.

The dropdown would allow selecting the type of switch, and then the spinbox would allow selecting the index of the switch within that type range:

• Mem bit switch: 0-127 (0-127)
• Dan bit switch: 0-63 (128-191)
• Zone bit switch: 0-31 (192-223)
• Door-cleared zone bit switch: 0-15 (224-239)
• N/A Switch: 255 (no spinbox needed)
