Beginning work on connecting the smack api to the project.  Currently
doing the work in java...hopefully (and I believe) it will be easily
connected into the grails project.
Update initial testing for the MUC module between grails and vysper.
Right now all test run and are successful.
Added a bit of documentation to the XMPP server code/tests.
Move user functionality to a separate class, ChatUser.  GrailsServer
accesses this class and allows for it to call all that functionality.
Also, altered test cases to account for the change.  Updated
documentation for this as well.
Merge remote-tracking branch 'origin/XMPPServerClientSide'
