ZF-6880: Zend_Service_Twitter should implement the Twitter Block User API


Zend_Service_Twitter does not currently implement the methods from the Twitter API for blocking a user. Ideally, Zend_Service_Twitter should implement all available methods from the twitter API, including the Block methods.


Inital implementation of the blocking API code.

I need to update this patch to work with the updated twitter code.

I will get this done before the next release.

Checked into the trunk with r18505 and merged into the release branch with r18506
