Bukkit

Features :

• Added a debug_level parameter in the config file
• Thread synchronization errors are now shown as warnings when debug level is 1 or higher
• Debug level 2 or higher displays math informations each time the time is updated, useful when checking distortion accuracy

Fixes :

• ticks_between_updates is not settable to 0 anymore
• time distortions are more accurate when ticks_between_updates is small and multiplicator is lower than zero

time distortions tend to be extremely inaccurate when ticks_between_updates is really small (less than 5 in most of the cases) and multiplicator is lower than zero.
