Hello, I took a first stab at restructuring Virtualbox <https://wiki.archlinux.org/index.php/Virtualbox>. I brought in the content from Arch_Linux_VirtualBox_Guest<https://wiki.archlinux.org/index.php/Arch_Linux_VirtualBox_Guest>, and offloaded a bunch of stuff to VirtualBox_Extras<https://wiki.archlinux.org/index.php/VirtualBox_Extras>. Discussion of the changes on Talk:VirtualBox#Page_overhaul_by_dev_request<https://wiki.archlinux.org/index.php/Talk:VirtualBox#Page_overhaul_by_dev_request> .
