ID update!

Bugs fixed:

• When you place a named item in the backpack, it causes an error.
• Splash potions & lingering potions are now supported.

Changes:

• The backpack now saves the ID, not the item name. This resolves the potions bug, but will probably need to...

This version simply fixes the new bug added in 3.3, where data values of some items were being changed (like player skulls and dyes).

Thanks once again to MachisCZ for reporting the bug!

Updates in this version:

• The item data values are now saved and added to items, so they won't "repair" automatically when you open your backpack.
• Updated the version correctly in the script.
• Full translation added in the configuration.

This is a pre-release because the way I fixed the bug is not the best one. I should post the final version as soon as I find out how to do it in a better way (it works without bugs, but I didn't like it).
Special thanks to...

Now item swap is completely blocked while the backpack is opened. This should prevent any bugs related to placing a backpack into another.

Two bugs have been fixed:
o) You could put your own backpack into itself. Thanks to @DHStyle for reporting it.
o) The character to split at has been changed to " ; " to prevent any conflicts with NBT. So now items with big NBTs (like heads) are completely supported.

Other changes:
o) Backpack limit has been removed until I find a (good) way to limit to 1 the amount of backpacks in player's inventory....

I've forgot a small debug message in the code when you have two backpacks at the same time.

If you find any bugs, please report them in the thread.
