Added Storage's "Arrange Items" + Fixed equipped pet on CS issue

Implemented the "Arrange Items" Storage feature (merge & sort items on the Storage). Fixed items from different ownerships being merged together when trying to swap their positions. Fixed a bug where putting equipped pets onto Cash Shop inventory would cause a crash the returning to the game.
