Miscellaneous fixes

[Logg-y]

• Fixed treasure maps incorrectly having parts drawn with "artistic" approximation and other parts of the same line being shown with perfect accuracy. Existing treasure maps should not change solution location, but they might look a bit different now.
• Killing Port Llast Convicts after they surrender once again doesn't count as murder any more.
• Killing allies while they are in combat with something else no longer counts as murder, but they will still turn hostile (and fighting back will still count as murder once the 3rd party they are fighting is dead).
• Fixed the enemy dropping equipped item logic being able to drop multiple copies of the same item.
• Fixed lock bashing not being able to show "success not possible".
• Fixed stealth XP only being granted for one enemy per 6 seconds.
• Fixed Stranded Merchants buying items for more gold than anyone else in the module.

[Logg-y]

• Fix level 2 adventurers spawning with more equipment than intended.
• Fixed a treasure map in City Core that was inaccessible.
• Refactored area cleanup logic, which should fix various bugs:
  • Adventurers would get destroyed if they were in your party when the area that created them was cleaned up
  • Luskan Captain's district was not cleaning up all creatures, making it gradually fill up over time as more and more spawned to the point where this could lag the server up to the point of dropping people.
