All jobs widescan (retail).

Setting added to conf/map_darkstar.conf to enable/disable all jobs having widescan. Default is retail, alternate setting for playing like it's 2004!

The setting also attempts to set the radius tiers for bst and rng, data is based on what we had in traits.sql and wiki data.

Dummy trait removed - no longer needed. There is no trait data for widescan in client at all it was tacked onto resist slow until now.
