Bug Fixes
=========
* Game crashing under certain conditions in Online Lobby for game running on Windows 98 and Windows ME.
* An internet connection is no longer required to host LAN games.

People convicted of chronic cheating will no longer be flagged, as there was a bug early on that would convict people of cheating even when they did not cheat.
