[fw-auth] Zend_Acl fixes in trunk for assertions ZF-1721 & ZF-1722

Hi all,

I have supplied a fix in trunk for issues ZF-1721 and ZF-1722. This is
a long standing issue that affects developers who wish to write
non-trivial assertions. If anyone is interested, here is a similar use
case that describes part of the issue I think a lot of developers have
run into.

Please test out Zend_Acl from trunk and let me know if it fixes your
issues. The issues described in the issue tracker the fix affects are:

* Zend_Acl::isAllowed does not support Role/Resource
Inheritance down to Assertions
http://framework.zend.com/issues/browse/ZF-1721

* Zend_Acl assertions broken when inheritance is required
(ie DepthFirstSearch)
http://framework.zend.com/issues/browse/ZF-1722

* Resource objects passed in to ACL query methods are not
passed through to registered assert()'s
http://framework.zend.com/issues/browse/ZF-4460

* Assertion implementation does not receive ACL query
parameters.
http://framework.zend.com/issues/browse/ZF-5425

* Inheritage of roles: rules are checked by parent roles
http://framework.zend.com/issues/browse/ZF-3390

Thanks!
