Bot Looting-related fixes

[bozimmerman]

Fixes a bundle of bot looting issues:

1. Rogues will unlock dungeon chests for the whole party.
2. Bots engaging in gathering skills can successfully complete their gather by actually wanting to loot the results (fixed skinning, mining, herbalism)
3. Bots in a dungeon group roll-for-loot situation actually make a choice.
