admin feature: output all players / tournaments in system

[VestboyMyst]

maybe add a page for admins that generates a list of all players in the system across all region databases. if it can order them by some aggregate score it would be good for seeding events in tristate that have a combination of NJ and NY players

also something similar for tournaments. that way we can delete any brackets that are messed up / unused. currently the only way to delete a bad bracket is if it shows up in your region's tournament list

We could expand this idea into a search page, where you can search for tournaments by a bunch of parameters such as date rage, region(s), name, and also for Players by name, region(s), skill rating threshold. What do you guys think? @VestboyMyst @jessemtso
