Depend on individual Symfony components

[thkoch2001]

Before we used CCDNUserSecurityBundle, we had a list of the individual Symfony components that we depend on. Since CCDNUserSecurityBundle has a dependency on Symfony/Symfony we had to finally make the step to depend on the full Symfony distribution.
It was not such a problem in our case, but it might be for others. So maybe it would be better if CCDNUserSecurityBundle would depend just on the Symfony components that are real dependencies.

Do you know what would need to change in order that it does not depend on the full distribution?
