Request for review: new desktop groups - XFCE

[Sergio]

Another app that may be considered to be added to some group is a 
graphical package manager (gpk/yumex).
Also some of the system-config tools.

Last time I checked, xguest wasn't working. It hasn't been updated since 
but I may try to help debugging it, if it's the case.
Problem is that I have F17 and no space to install F18 but if xguest 
works properly, that's a package I would also include.
