Add compatibility with Group Advantage implementation

[Jagusti]

• The following Advantage automation settings are ignored, as if they are disabled, when Group Advantage is being used:
  • Suffering a condition.
  • Losing momentum (individual momentum is not applied if Group Advantage is used).
  • Adding to combat (if Group Advantage is used, the system handles syncing individual advantage with the group).
• Only Advantage gains from Opposed Tests and Outmanoeuvring are applied (losers do not lose Advantage automatically when Group Advantage is used).
• Advantage gain is not flagged when a combatant charges.
• Removed user notifications reporting individual Advantage changes. Reasons for change (such as "PC outmanoeuvred NPC") are still shown, though may linger longer than Group Advantage. messages if they are set to persist.
• Updated setting hints to indicate where Group Advantage bypasses individual Advantage automation settings.
