app/library/Bootstrap.php: revove "Application" and add "Services" class with the services definitions.

Had some wierd problem with closures an $this when being defined in one class and used in another
(defined in Application, used in Phalcon\Di\FactoryDefault).

So we move all of this to "Services" class that directly extends FactoryDefault DI.
And therefore, we don't need a Application class anymore.
