* This commit moves taking screenshots of hosted servers onto the strikers using the Sys::Virt module. This was needed because the screenshots were being taken by scan-server, and that was causing it to take a long time to run. It should never have been handled by the scan agent anyway. This update requires a WebUI fix to use the new screenshot tool. This tool also adds holding multiple screenshots to allow users to "scrub" through screenshots up to 10 hours in the past.
