(WIP) Lottery Statistics

Edit: I will probably not return to this as a project, so here is the code if you want to collect stats yourself

Stats are in the format "<unix time (ms)>,<winner username>,<amount won>,<winner's tickets>,<total players>,<total tickets>\n"

Uses MCProtocolLib

I don't need it to be particularly professional, just reasonable looking enough to make it comfortable to the eyes
As for the user profile thing, I don't want to have to have people register, but I was trying to think of ways you could enter your username and verify with the bot ingame so you didn't need a password. choosing to stay logged in if desired
