Add analytics (gross)

[audiodude]

As much as I hate it, I think we need to add analytics. Currently, we're looking at the count of users in the database to roughly gauge how popular the site is. Assuming it starts to get more popular, it would be important to know, at the very least, how many people are visiting the site in order to, at the very least, do capacity planning.

Google analytics is straight out, so we'll have to find a solution that isn't completely privacy violating.
