Adds a PandA (previewandaccept: accepts a HIT from within in the group at random) link/button. Adds a Pick & Roll button that accepts the very HIT you are previewing (if still available) and then skips to a new HIT. Adds the automatically accept checkbox to HIT previews. Shows the Accept button and CAPTCHAs right away. Adds a RandA button that returns a HIT and loads the HIT's PandA URL. Makes the Return button red.
