Traps&Detection
Actor:canSee correctly calculates and uses the correct chance to see when the target has both Stealth and Invisibility. ESP only helps seeing actors, not traps, etc.
Actors get a chance to detect traps when they are placed.
Game:logVisible does a better job at determining when non-actors are identified by the Player in log messages. Updated the comments for the log management functions.
Actor's combat.talented field is set to "disarmed" by default.
