[bug] global variable "index"

[LoeiFy]

hello, i find vibrant.js will set a global variable index

https://github.com/jariz/vibrant.js/blob/master/dist/Vibrant.js#L143

i think this can fix it

// https://github.com/jariz/vibrant.js/blob/master/dist/Vibrant.js#L134-L152
        count: function(force) {
            var vbox = this,
                histo = vbox.histo;
            if (!vbox._count_set || force) {
                var npix = 0,
                    i, j, k, index;  // add index here
                for (i = vbox.r1; i <= vbox.r2; i++) {
                    for (j = vbox.g1; j <= vbox.g2; j++) {
                        for (k = vbox.b1; k <= vbox.b2; k++) {
                            index = getColorIndex(i, j, k);
                            npix += (histo[index] || 0);
                        }
                    }
                }
                vbox._count = npix;
                vbox._count_set = true;
            }
            return vbox._count;
        },

Realized it's actually a bug in the quantize dependency, not vibrant.js.
