[Feature request] Associating with custom extensions

[matthew-dean]

Is there a way to associate this plugin with extensions that are not .css, .pcss, or .postcss? If not, can this feature be added? Looking for a quick way to support this: jesscss/jess#25

Ah, never mind, figured it out!

    "files.associations": {
        "*.jess": "postcss"
    }
