This is a very naive and primitive logger of user requests to the game.
To be used on systems where access to webserver's log data is not
available (especially if the webserver doesn't store POST data as well).
Because the check changed to see if /var/installed is present (and it
would never be in the version previously installed), this caused some
pages to redirect to /install.
A lot has happened here. Here's the list:
1. autoloader was added that should prevent various "failed to open
stream" errors when trying to load new classes
2. PHP-based data generation was replaced by MySQL-based one, hopefully
fixing the installation problems when insert payload it too high and the
DB wouldn't populate with some users
3. thanks to step 2, the installation should be really almost
instantenious, instead of waiting a long time for many SQL connections
and queries to populate the world
4. World Data & Oasis generation and population is done in 1 step now
