[PackageDev] Add support for var()

Description

The support for PackageDev themes and color schemes is great - it’s what I most often use this plugin for. Would it be possible to add previews for the simple "var(some_color_variable)" syntax?

For example, in a color scheme, I define a variable and then use it for a global:

{
    "variables": {
        "blue": "#0042FF"
    },
    "globals": {
        "selection": "var(blue)"
    }
}

The color preview shows up next to the #0042FF as it should, but I would like that same preview to show up next to var(blue). I don’t use any of the color() mod function options, but I imagine those that do would probably like to see previews of those, too (if possible, given they’re implemented within Sublime and not exposed via the API, that I know of). However, even if you can’t do that or it would take a long time, I should think it would be fairly straightforward to highlight var(). Unless the variables themselves are made using color()…

Can you elaborate? I’m not sure what your mean.

Oh, I meant in the context of the command palette.
