This is a work in progress to add ZendFramework 1 support into TESessionBundle

Please add type hint: array $zf1Namespaces

And please add PHPDoc every where

IMO we should not create a new item in the configuration to add namespaces for a specific framework.
The most elegant way I can think of is to add a namespaces attribute in the configuration and inject it in the BagConfiguration used by the user.

In the end the configuration would look like (and taking into account my remark in #12:

theodo_evolution_session:
    bag_manager: theodo_evolution.session. zendframework1_bag_manager
    bag_manager_configuration: theodo_evolution.session. zendframework1_bag_manager_configuration

    namespace:
        - foo
        - bar         

And it will symplify a LOT of code in the extension too 😄

This is a great idea 👍
