zBag - A single window inventory management addon.

Goals:
1) Be able to retrieve item information when hovering the mouse over the icon (partially done)
2) Be able to switch item slots using the Inventory window (done)
3) Add the ability to use items directly from the addon
4) Replace the "open bag" hotkey with the addon hotkey
5) Bank Management (Very low priority, only after inventory management is done)

Current commands:
/di ==> This will display the item list in the Inventory window. Basic item management is possible.
/pb ==> This will display the item list in the chat window.

Known Issues:
- Tooltips doesn't follow mouse cursor (Rift command issue, not fixeable for now)
- Unable to use items straight from the addon, since this is an addon API limitation.
