Bukkit

Added a chunky reload command which makes it possible to load changes from saved tasks without restarting the server.
Added confirmations for when you try to start a task when one is already saved, or when cancelling tasks. This should save a lot of people from headaches and lost work!
New Polish translation added, thanks to xxneox, and the Russian translation was also updated.
Fixed a bug where continuing a task where the chunk count is higher than the maximum (when entered manually) would cause weird behavior.
Fixed a bug where cancelling a saved task would set the time incorrectly.
