Serialise form data bug

[pdscopes]

When you have a input name like foo[8.8.8.8] serialising the form data into JSON creates:

{
  "foo": {"8": {"8": {"8": {"8": "VALUE"}}}}
}```

Rather than the expected:
```json
{
  "foo": {"8.8.8.8": "VALUE"}
}```

Could be solved by using escape character \.:

    convertTo: function (name) {
        return name.replace(/\./g, '\\.').replace(/\[]/g, '.*').replace(/\[([^\]]+)]/g, '.$1');
    },
    set: function (object, key, value) {
        if (null === key) {
            return object = value;
        }

        var rev = key.split('').reverse().join('');
        var keys = rev.split(/\.(?=[^\\])/g).reverse().map(function (x) {
            return x.split('').reverse().join('');
        });
        // var keys = key.split('.');
        var temp = object;

        for (var k=0; k<keys.length-1; k++) {
            key = keys[k].replace(/\\\./g, '.');
            if (key === '*') {
                key = Object.keys(temp).length;
            }

            if (typeof temp[key] === 'undefined') {
                temp[key] = {};
            }

            temp = temp[key];
        }

        key = keys[k].replace(/\\\./g, '.');
        if (key === '*') {
            key = Object.keys(temp).length;
        }
        temp[key] = value;

        return object;
    }
