Denis reported that receive(0) returned messages.

This bug is present in the Db & Array adapters.

This has been fixed in all adapters.

In Zend_Queue 2.0 we need to make a requirement that all messages must be 0 
or higher and negative numbers will throw an exception.

* Updated code to put bulk of receiving code in if ($maxMessages > 0)
