Subject: [PATCH] add missing property

Even if every class inherits from stdClass allowing us to add properties on runtime, i believe it's better to declare them.

I also think that we should add service properties (those fetched from the registry/service-provider), smt like:
```php
	// User properties
	private $user_id;
	private $user_group_id;
	private $username;
	private $permission = array();

	//services
	private $db;
	private $request;
	private $session;
```

or as i always do, with doc-blocks to allow type-hinting and code completion
```php
	// User properties
/**
 * @var int
 */
	private $user_id;
/**
 * @var int
 */
	private $user_group_id;
/**
 * @var string
 */
	private $username;
/**
 * @var array
 */
	private $permission = array();

	//services

/**
 * @var DB
 */
	private $db;

/**
 * @var Request
 */
	private $request;

/**
 * @var Session
 */
	private $session;
```
