Confusion with the pre-releases.

While Minecraft 1.7.3 isn't released.... People can already have 1.7.3 pre-release even when snapshots aren't checked in the options.

This makes for some unneeded bug reports and some confusion for people who (don't bother to check sites and such) or aren't up to date.

Dinnerbunny, if possible, maybe the pre-releases should come only to the people who have snapshots enabled?
