Bukkit

• Updated Event Handlers & other methods to be R6 compliant.

Fixed Bugs:

• /sell all now works for data values correctly.
• Taxes now work for tools with varying durabilities.
• Gunpowder now works
• Changed some Auto-Updater settings; instead of accessing my server for information, I have a dedicated 100% uptime website that it retrieves update info from, and the file will be stored on dropbox. This should prevent any errors from AutoUpdater about not being able to reach the URL.
