Title: Describing memory spooling in combination with console command

As discussed (https://github.com/symfony/SwiftmailerBundle/issues/23), when memory spooling is active and one tries to sent mails from a console command, nothing happens because the kernel terminate doesn't get called.

I tried to find a good place and think the email cookbooks are ok. I didn't want to put it with the console documentation as the console is a stand alone component and the docs are written in a general way. The behaviour described above on the other hand is related to how symfony works with the events.
