PHPUnit integration

[jakzal]

Should allow to do the following in phpunit tests:

class FooTest extends \PHPUnit_Framework_TestCase
{
    use PHPMatcherAssertions;

    public function test_it_asserts_if_a_value_matches_the_pattern()
    {
        $this->assertMatchesPattern('@integer@', 'foo');
    }
}

Failed asserting that 'foo' matches the pattern.
"foo" does not match "@integer@" pattern

For PHP 5.3 PHPMatcherTestCase is provided.
