Sort order fallback: Add `yandex`, `zen` and `csscomb`

[tonyganch]

From discussion with @matmuchrapna:

Allow using sort orders from predefined configs as sort-order-fallback option. For example:

{
  "always-semicolon": true,
  "sort-order": ["color", "..."],
  "sort-order-fallback": "yandex"
}

// Before
a {
  left: 0;
  color: 0;
  top: 0;
}

// Before
a {
  color: 0;
  top: 0;
  left: 0;
}

From issue's description it's not clear that I want not exact sort-order-fallback, because it will not work without sort-order, but I should not be required to define my own sort-order if I want to use sort-order from predefined presets.

@matmuchrapna, you can just define in config: "sort-order": ["..."]

ok, but will look like hack, wouldn't it?

How about just adding a preset option to get all values from a predefined configuration and then extend it with the user defined values. Very similar to jscs presets

example:

{
    "preset": "zen",
    "always-semicolon": true,
    "color-case": "lower",
    "block-indent": "    ",
    "quotes": "double",
    "sort-order-fallback": "abc",
}

This not only solves sort order fallback but allows end user to leverage all existing configs with just a few tweaks to match their taste.
