Xfce spin Beta RC3 validation pass

[Adam Williamson]

Quick note - per my testing, Beta RC3 desktop spin passes the validation
testing for Beta, with a clean slate except for
https://bugzilla.redhat.com/show_bug.cgi?id=636229 which I noted in
passing. Great job!

testing from others to confirm is still welcome! I'm not always right =)
