Updated Perl modules: Spread::Session, Spread::Queue

[Jason W. May]

Just posted to CPAN:
        Spread-Session-0.2
                Spread::Session - OO wrapper for Spread messaging toolkit 
        Spread-Queue-0.3
                Spread::Queue - One-of-many queued messaging delivery, using Spread 

No significant functional changes.

I've added some test cases.  I might elevate these from alpha to beta shortly.

I've successfully tested Spread::Session end-to-end with Guido's
Python module.  There's plenty more cross-language work to do.

Cheers,
-Jason
