Add new places for Guildbank

Hi, i'm officer of 80's guild and, my guildmaster notified me:
The places from the guildbank is too limited.

I propose to add some items from Database Cataclysm to add more tab like this:

- Guild Vault Voucher 7th Slot -> https://www.wowhead.com/item=62286/g...ucher-7th-slot
- Guild Vault Voucher 8th Slot -> https://www.wowhead.com/item=62287/g...ucher-8th-slot

I think isn't much harder to take the item from Database and rework it on Warmane TLK.
I wrote this ticket because can't suggest it on Shop pannel cauz items did'nt exist in database wotlk.

I think that can be most helpfull for a lot, and can be a new benefit of coins for Warmane.

Thanks for reading. Pray for acceptance.
