Let define syntax for extensions; Fix #6

[isqua]

Discussion: #6
In .csscomb.json:

{
    "syntax": {
        ".css": "scss",
        ".lss": "less"
    }
}

If the implementation is ok, I’ll write tests.

You want to use _extractSyntax in this place too.

If the implementation is ok

It is. Thank you 🐘

You can't be sure that map was copied because {} is the default value it gets even if configuration fails.
I'd offer replacing on line 27 syntax: {} with syntax: {'.css': 'scss'}, for example.

assert.equal check pointers, not values:

assert.equal({}, {}); // => false

let a = {};
let b = a;
assert.equal(a, b); // true

...

Good to know, thank you!

Is Map usage ok? If so, I’ll squash commits.

[tonyganch]

Map is ok. Let me know when to merge.

[isqua]

It’s ready to merge now 🔥
