Support wildcard as port number

[0xiso]

If a wildcard is used as a port number, for example default-src http://example.com:*, it will cause an error like shown below. This pull request will fix this.

> parsed = new parser.CspParser("default-src http://example.com:*").csp;
Csp { directives: { 'default-src': [ 'http://example.com:*' ] } }
> new evaluator.CspEvaluator(parsed).evaluate();
Uncaught TypeError [ERR_INVALID_URL]: Invalid URL
