Clone Zoo ZX - Joystick support added

Great news for those of you asking for Joystick support. We've been hoping to get this in from the start (without breaking things) and  it is now working. We've attached a separate version of the game clonezooJ.tap so you can try it out.

If using an emulator you may need to configure your settings to get it working.
Feel free to send feedback and configuration tips below.
