Fix #42 without disabling ghosting indicators

Currently when dealing with #42 this was fixed by just wrapping SetColor in a if APG.cfg["ghostColorToggle"].value then statement.

I feel like a more elegant solution would be to check when an object has duplicator.DoGeneric on to it, and grab the colour data from there so that the ghosting can work as intended with the intended visual indicators.

While I feel this would be a better solution, I think it's still a good idea to give people the option to disable the ghosting color.

Yeah the option is nice, but it might be confusing for some users. Plus it doesn't fix the actual issue, just works around it.
