Some space pruning on Xfce spin

Greetings. I did a bit of pruning today on the Xfce spin, as it had gotten way way over sized. +-adobe-source-han-* # save 94MB +-rodent-icon-theme # save 34MB +-skkdic # save 25MB +-naver-nanum-gothic-fonts # save 14MB I also remove liferea from the comps group (this pulled in webkitgtk3 and should save us a good bit of room) I also added evince (we had no pdf reader and it was pretty small) and gvfs-archive. I suspect we will still be over, but we can see tomorrow how much and see what we might be able to further adjust. kevin
