Added support for annotations in parent methods, when method is not overwritted in current class

Example:

class A()
{

    /**
     * Secure(roles="ROLE_AMIN")
     */
    public function AA()
    {
        echo 'engonga';
    }
}

class B extends A
{

}

Previously, class B method AA() is not secure because main class of method is not the same as current class.
By adding ( If is current class or is subclass of ) this case is solved.

Tests are OK.
