* Caching IP to host data for only 10 minutes isn't going to cut it. If your server is very slow, users will always get a long slowdown every 10 minutes, so I'm upping this to 24 hours, and hopefully it won't clutter the cache folder with IP data. Seriously, I had to go through a xdebug session just to get to the bottom of this and understand why my local server was so slow when accessed remotely, and so fast from my localhost (answer: 127.0.0.1 is easy to translate.)

* If the IP to host process is really slow and the admin never went to the admin page for this (which is unlikely, but on a first launch maybe...), disable hostname lookups by default. Once the setting is changed manually, it'll never be overridden again. BTW, totally untested... Don't complain too much, I'm doing this between two bottles for little Charlie. (Subs.php)
