Changes regarding storage implementation on ManaMarket

[Meistache]

Finally.

What's done until now:

• Storage class for keeping a local storage and manipulating storage;
• Added storage packets to protocol.py;
• Added new item trees and their data templates:
  • Delisted tree deals with expired items in the sale tree list;
  • Stack tree allows someone to add an item even that inventory is full, so it will be added to list as soon as it's free;
  • Added changes to main.py to comply with new features.

What needs to be done:

• storage_open (through @storage command) is kicking MM off;
• do_delist must take items from stack tree and add to sale tree (my bad; just remembered it now... gotta make a new commit soon)

[Meistache]

Added a unstack() function since it's done on SMSG_PLAYER_INVENTORY_ADD as well as do_delist, which is making sense now with it.

So now the only thing is about opening storage without a buttkick.

The kick is from the
clif_validate_chat(): TestRun (ID 2000000) sent a malformed message: spoofed name/invalid format.
The first Open Storage is kicking the bot.

Figured it out.

I will try to test this later tonight. unless someone tests this on test first.

@Meistache this is the current version of Mana Market on the test server.
