Fixed bug when the parser stopped working met statement unnamed.

[vladkens]

The CSS:

b { color: red; }
{ color: green; }
a {color: blue; }

earlier parsed to

{
    "type": "stylesheet",
    "stylesheet": {
        "rules": [
            {
                "type": "rule",
                "selectors": [
                    "b"
                ],
                "declarations": [
                    {
                        "type": "declaration",
                        "property": "color",
                        "value": "red"
                    }
                ]
            }
        ]
    }
}

now

{
    "type": "stylesheet",
    "stylesheet": {
        "rules": [
            {
                "type": "rule",
                "selectors": [
                    "b"
                ],
                "declarations": [
                    {
                        "type": "declaration",
                        "property": "color",
                        "value": "red"
                    }
                ]
            },
            {
                "type": "rule",
                "selectors": [],
                "declarations": [
                    {
                        "type": "declaration",
                        "property": "color",
                        "value": "green"
                    }
                ]
            },
            {
                "type": "rule",
                "selectors": [
                    "a"
                ],
                "declarations": [
                    {
                        "type": "declaration",
                        "property": "color",
                        "value": "blue"
                    }
                ]
            }
        ]
    }
}

cool, test please!

[tj]

although we should maybe just output an error there

[vladkens]

Sometimes I see in CSS such constructions. Don't think this is really critical.

[vladkens]

But you decide. Maybe can and throw an exception.

[jonathanong]

personally i'd rather throw an exception. is that even valid CSS?

eitherway, you need a rebase and squash

[benschwarz]

Its invalid, an exception should be thrown.
