Added the edit subcommand - it is now possible to edit the bag's items in-game with an inventory.
Added the save subcommand to save the inventory into the configuration of the bag.
Removed the items and additem subcommands.
Added wintersday-gift bag with a variety of colorful items for the holidays. Currently the drop chance for the wintersday gift is zero (that is, it will not drop from mobs until the configuration is changed).
