Expand Statistics Page #3180

It would be nice if the statistics page had information on a few more different stats such as voting data (from both data collection and chat, amount of messages ranked, number of messages generated in chat (and regenerated), and potentially the amount of messages ranked from #3044. The data from the data-collection side could be by language but data collected from the chat side would probably need to be language-agnostic since people may not always be chatting in the language they currently have set. The voting data could be displayed as a pie-graph which shows the ratio between up and down votes.
