Add toggle for Snap Color in settings

[177013IsNice]

Is your feature request related to a problem? Please describe.

I feel like given the lack of skinning knowledge of the community, it would be nice to include a button in settings to toggle snap colors but only if the skin contains snap colored variants of hitobjects. I personally feel this would fit nicely under the Configuration section in the Skins setting. It just feels like a nice simple quality of life feature that makes Quaver feel even nicer.

Describe the solution you'd like

To make sure all skins are compatible, the switch would only be visible if the skin either contains a spritesheet for snap colors, or at least has snap colored variants of the hitobjects.

Describe alternatives you've considered

The current method of telling people to go to the .ini and change it works but only to a small extent, since to people who don't skin, the ini looks like a wall of text.
