Phalcon7 1.2.3发布更新，增加Wiredtigger存储

使用 WiredTigger 实现本地存储，用作数据缓存。在本地测试每秒可以达到10万的插入（CPU:Intel(R) Xeon(R) CPU E5-2403 0 @ 1.80GHz、Memory:8GB）

$db = new Phalcon\Storage\Wiredtiger('unit-tests/cache/wiredtiger');
$this->assertTrue($db->create('table:phalcon_test'));
$cursor = $db->open('table:phalcon_test');
$this->assertTrue($cursor->set("key1", "value1"));
$this->assertTrue($cursor->set("key2", "value2"));
$this->assertEquals($cursor->get("key1"), "value1");
$this->assertEquals($cursor->get("key2"), "value2");
$this->assertEquals($cursor->gets(array("key1", "key2")), array("value1", "value2"));
$this->assertTrue($cursor->delete("key1"));
$this->assertEquals($cursor->get("key1"), NULL);
foreach ($cursor as $key => $val) {
	$this->assertEquals($key, 'key2');
	$this->assertEquals($val, 'value2');
}

查询参数支持绑定数组：

$songs = $manager->executeQuery('SELECT * FROM Songs WHERE id NOT IN (:id:)', array('id' => array(1,2,3,4)));
