Breaking changes: implemented global weight inventory system, read description before updating!

- Fixed #256
- Implements #173

__NO OFFICIAL ESX SCRIPT WILL WORK WITH THIS AT THE MOMENT__

This commit will break your entire ESX if you dont use the new SQL format, follow the new one if you want it all to work properly.

Scripts using `item.limit` will break too, instead use `xPlayer.canCarryItem(item, count)`
