(Do Not Merge): PvP Vendor Progression pseudo-module for TBC

[Gultask]

Added here to better keep track of it.

here's the barebones PvP query. The SET commands allows to customize prices for each tier on each season they're available. Current prices there are taken from TBCMangos. Should all have condition for each class built already, as well as slots to better organize it.
Again, this is a custom implementation, and far from a faithful recreation of TBC Arena seasons.
all creatures are tied to game events, so just .event start 75, 76, 55, 56 and their inventories will change accordingly

There's also a Phase 0 bracket that is tied to season 8 (game event 60)

Just release this under its own SQL query repo.
