[Feature] Implement 'disenchant' mode in raids and dungeons in vanilla and tbc

[dsidirop]

• Wotlk 3.3 has built-in auto-disenchant so it seems it doesn't need this feature all that much

• However there are some small improvements over the original implementation that they didn't think about:

We can keep track of the looted items + total amounts of enchanting mats generated during a raid/dungeon
Help with accurate disenchanting of looted items p.e. via cli '/zende' (+ info printing in the party chat for the sake of transparency)
Auto-distributing the mats in the party members in the end of the run (kinda useful - maybe there is another addon out there that does this)
