Delete IP address and UUID fields from database

[jrddunbr]

For GDPR compliance, let's delete the IP address and UUID fields from the database.

In a future release of the game, we might allow sending the username (or the user's uuid) with the request and that would be an opt-in feature that is easy to comply with GDPR requirements in the future.

Once those fields are deleted, I'll be dumping the table in the garbage so that any data we've collected so far is discarded, since technically it can't be compliant (and honestly it would only capture developers anyways since the code is unreleased, so let's just delete it).
