Another request for inclusion in 0.18

[Robbie Gemmell <ro...@gmail.com>]

Hi Justin,

I would like to request that the following JIRA/commits be considered for
inclusion in 0.18:

https://issues.apache.org/jira/browse/QPID-4167
http://svn.apache.org/viewvc?view=revision&revision=1367796
http://svn.apache.org/viewvc?view=revision&revision=1367797

These add tests for and fix various issues to do with creating and viewing
queues via the Java brokers new web management interface. The first
addresses parameter type issues during queue creation, and a
ClassDefNotFoundException which would occur when viewing queues with
messages acquired by consumers. The second contains a fix to prevent
infinite'ish looping during output of JSON data for queues with an
alternateExchange configured, and adds the ability to request DLQ creation
to match the already-present maxDeliveryAttempts option (thus allowing
people to actually use that without incurring message loss). Both commits
also contain a small amount of cosmetic rearranging of the UI.

The changes are rather trivial, very isolated to the new http management
bits (and mostly the .js and .html at that), pose no risk to operation of
the broker itself, and contain fixes for defects that would render much of
the new management UI unusable for most users.

The changes were made either by Keith, Alex, or myself, and mostly done
while we were pair programming.
