Update FarmHud_TrailPath.lua to fix trailPathOnMinimap rotation and icon selection

[Sockdolager]

Update definition of lsOnCluster to include FarmHudDB.trailPathOnMinimap so icon settings apply to normal minimap trail

Updated facing code to account for normal Rotate Minimap being turned off/default

Updated local pinIcon fallback

Updated entry:UpdatePin() to IsOnCluster
