This fixes a bug with headless replay of files, specifically those created by pyrdp-convert.py which seems to set the timestamp to 0. Using the timestamp is probably bad anyway due to the risk of collision.
This fix artificially accelerates all replays when played in pyrdp-player.py because it squeezes all events together leaving no silence between events. It cannot be merged like that.
