Feature Req: Add Yandex reverse image search

[EC-O-DE]

Yandex? It's very good image reverse engine. Usually Google finds more sizes better, but Yandex is better at providing similar images.

[EC-O-DE]

to search from Yandex it's something like this:

/* This is the Yandex image search command. */
CmdUtils.CreateCommand({
name: "ya-image",
takes: {"text": noun_arb_text},
icon: "http://images.yandex.ru/favicon.ico",
homepage: "http://images.yandex.ru",
author: {name: "Alexey Fedoseev", email: "aleksey@fedoseev.net"},
license: "GPL",
description: "Yandex images search",
execute: function(input) {
var location = input.text;
var url = "http://images.yandex.ru/yandsearch?text=";
url += encodeURIComponent(location);
Utils.openUrlInBrowser( url );
}
});
