TBag - Inventory Only

• build(TOC): 10.2.7.02 release
• fix(Tokens): Make tokens update appropriately as their value changes

In Events.lua:

• Add event registrations for CURRENCY_DISPLAY_UPDATE and TRADE_CURRENCY_CHANGED
• Point to newly renamed TBag.Tokens.ScanAndUpdate function

In Tokens.lua:

• Remove unnecessary function hook of TokenFrame_Update (we're using an event now)
• Add some debug prints
• Rename TBag.Tokens.Hook to ScanAndUpdate, since we're no longer hooking and this more accurately describes its function

In TInv.lua:

• Fix some spacing
• Remove reference to now removed TBag.Tokens.Enable function
