v1.0.15 - Fixes + Convergence build

v1.0.15 is the first release of the Convergence build — ~7200 icons
generated from The Convergence's own game data (built against 2.2.3.1),
including its relocated loot, new bosses and reworked zones.

Changes in v1.0.15 for the ERR and vanilla builds:

• Defeated NPC invaders now get the kill checkmark on their markers
  (all quest invaders covered; after the Sellen/Jerren confrontation
  both markers complete, whichever side you took).
• Invader markers that sat away from the actual fight were moved to
  where the fight happens (e.g. the Knight of the Great Jar duels).
• Removed phantom treasure markers for loot the game never awards
  (corpses with two bound treasures only drop the last one).

Changes in v1.0.15 for the vanilla build:

• Fixed missing boss names and zone labels on Shadow of the Erdtree
  markers (texts are now read from the DLC text layers).
• Two gathering nodes in Altus that were wrongly hidden are back.
