(svn r3547) - [Patches]: do some general cleanup, commentarization before starting actual work. This patch contains no functional changes (I hope). It might break GPMI-builds though when trying to join a trunk/ network game or vice versa. To solve, you can change the order of the first 8 enums in SettingDescType. I think that'll work.
