Palettes are duplicated if color class is in multiple targets

[fraserscottmorrison]

My Color class is included in my main project's target but also in an extension

I am seeing the palettes duplicated and I imagine its because both targets have been built, each added the palettes

I've fixed it for now (develop branch) as there's no downside for now, but because they are technically different classes in different modules, I might have to show them both at some time in the future, depending on what feature i end up implementing...
