Sort differs from ampersand-collection

[herregroen]

The sort functions used by this package and ampersand-collection are not equivalent.

Ampersand-collection uses it's own method while here lodash.sortby is used. I'm getting different results.

Overwriting _sortModels to use the following fixes the issue:

bind = require('lodash.bind');

...

    _sortModels: function (newModels) {
        if (this.comparator) {
            newModels.sort(bind(this.comparator, this));
        } else if (this.collection.comparator {
            newModels.sort(bind(this.collection.comparator, this.collection));
        } else {
            // This only happens when parent got a .set with options.at defined
            this._runFilters();
        }
        return newModels;
    }

The code in ampersand-collection is a custom build and is in need of swapping out for the lodash version, There's an issue in that repo for it here AmpersandJS/ampersand-collection#59

I am also getting wierd values with this version. I used a function with a single argument to return a value for the item to be sorted on, but that gave broken results.
