Add session and httpRequest services

....because if I use other extension which modify httpRequest or session (for example https://github.com/drahak/Restful/blob/master/src/Drahak/Restful/DI/RestfulExtension.php#L163-L164) my application is aborted with:
 *Service '0.panel': No service of type Nette\Http\Request found. Make sure the type hint in Kdyby\SessionPanel\Diagnostics\SessionPanel::__construct() is written correctly and service of this type is registered*
