[jboss-as7-dev] Using Guava in a subsystem

[Brian Stansberry]

Unless the module.xml for org.jboss.as.weld:main was wrong, this is not 
a new dependency. I see guava listed as a dependency at least as far 
back as 7.1.2.Final.

So even if there was a great argument for keeping it out, it's too late 
now. :)
