Fix upvotes in upvote box on left, add mongo server localhost connection

Placed upvotes in dummy upvote box, added a global variable in the mongo file to allow easy localhost connection to server.
Yeah, I think another way to handle this would be to load up a file ignored by git in the index.html conditionally that contains a bunch of environmental variables which need to be present when testing on a local box. Have you been setting environmental variables on your local box somehow?
