Special Debug Version in Public Beta

Now in the public beta branch, a special version of the game (v2.0.4 - AchDebug) with extra debugging code when recording achievements to the server, to help us figure out why sometimes achievements are not recorded. If this happens to you, please press F11 and submit a bug report.

UPDATED with AchBeta3, with more debugging.

This beta is identical in all other ways to the released patch 2.0.4b.
