Added isIp() pattern expander

[thomasbisignani]

This PR adds an isIp()pattern expander, it is based on the PHP filter extension.
This pattern checks IPv4 and IPv6 addresses within public, private and reserved range.

Example usage :

if (!PHPMatcher::match("127.0.0.1", "@[email protected]()", $error)) {
    echo $error;
} else {
    echo "Matched.";
}
