新增 `Phalcon\Storage\Btree` 类，测试插入10万数据，7秒左右。[code]$btree = new Phalcon\Storage\Btree(__DIR__.'/cache/tree.db');
for ($i = 0; $i < 100000; $i++) {
$btree->set('key_'.$i, 'value'.$i);
}[/code]基本操作：[code]$btree = new Phalcon\Storage\Btree('unit-tests/cache/tree.db');
$this->assertTrue($btree->set("key1", "value1"));
$this->assertEquals($btree->get("key1"), "value1");
$this->assertTrue($btree->delete("key1"));
$this->assertEquals($btree->get("key1"), "");[/code]主要更新内容：
Add class Phalcon\Storage\Btree
Add method Phalcon\Dispatcher::hasParam
Fix bug about class Phalcon\Chart\Qrcode
Fix bug about method Phalcon\Mvc\Model\Query::_prepareInsert
Fix bug about method Phalcon\Security::checkToken
