UI: Conning color adjustment

[Kai Moon]

In uiTarget.c, getConningColor() compares level and rank, capped at diff=4 (purple). This gives a player running +4 notoriety less UI information about targets; almost every target is purple, regardless of rank.

 

Adjusting plvl by adding the player's notoriety level, or some other optional player-chosen value, would give some players a more useful UI. For example, a level 50 player with a +4 adjustment would see level 54 minions as white, level 54 LTs as yellow, level 54 bosses as orange, etc.
