#015748: generator tag in atom feed invalid

Creating an atom feed with ezcFeed gives:

<generator>eZ Components Feed<version>1.2.1</version><uri>http://ezcomponents.org/docs/tutorials/Feed</uri></generator>

but it needs to be:

<generator version="dev" uri="http://ezcomponents.org/docs/tutorials/Feed">eZ Components Feed</generator>
