Wilderness improvements

Added an extra option to the deep wilderness gate warning: "I wish to proceed, and don't ask me again"
Reused the same warning, with appropriate changes, for the edge/ardy levers due to the pvp mechanics
Removed the interface warning when crossing the ditch until doomsayer is implemented
Removed the inauthentic threat revenant and restricted brawler/pvp drops to revenants and chaos elemental only
Now require 100k risk to obtain the boosted deep-wildy drop rates
Hid our inauthentic mechanics behind a new server config option enhanced_deep_wilderness
