Java Edition Classic 0.0.19a 04

0.0.19a_04 was a version of Classic released on June 20, 2009.

Fixes

 * Tried again to fix a bug where the client incorrectly throttles players that get kicked for running too fast, due to the client sending movement data while downloading a level.
 * This fix again did not work.
 * Notch said that this was caused by a bug in the sampling of his time adjustment code.
